Yeah except you also excluded the Europeans who beat the Americans to get twin jet-engine airliners into service as the French had the Caravelle and the British had the 1-11

@@asif9700 No idea where you are coming from (my ten cents: US), but here in Europe at least some streaming offers are being geo-blocked because of the rights of broadcasting certain movies, events and so on.

My dad was an engineer at Douglas specializing in landing gear stress analysis (using a slide rule, but that's a different story.) He was on the DC-9 (and by extension the MD-xyz) project from the time before it came off the drawing board until long after the merger. Even after it was out of production, he still worked on it. In those days you used to keep analyzing failures to support the operator even if no new aircraft are being built. Long story short, he spent the vast majority of a 40-year career working on that one design and its variants. Thanks for the good memories.

[@magnusolert1195]

"In those days you used to keep analyzing failures to support the operator even if no new aircraft are being built." The industry still does that.

[@gendaminoru3195]

did he have a machine shop overhauling landing gear in Riverside or thereabouts after he retired?

[@msromike123]

@@gendaminoru3195 No. He was pretty handy, but he really was a stress engineer first and foremost. He did have a go bag with calipers and specialized measuring tools, so he could fly in and show the operator how their maintenance procedures caused failures, such as wheels coming off, etc. (Not pointing any fingers Hawaiian Airlines.)

[@WOFFY-qc9te]

@@msromike123 Some data can only be collected after time has done a job on the component, the more quality data the better the estimate of mean time between failure.

[@fleipeg]

Just prior to Eastern closing it's doors I booked a flight from Miami to Atlanta to visit my girlfriend. The DC-9 we flew was stopping in West Palm Beach (we picked up 18 more passengers) before continuing on to Atlanta. Well, on the Miami to Palm Beach leg I was the ONLY PASSENGER! I couldn't believe it. What added another layer of humor to the whole thing was that one of the flight attendants quizzed me on the emergency procedures instead of briefing them (asked me questions like.... where are the nearest exits, etc). She and I were laughing as she asked the questions. Its such an amazing memory that it brings a smile to my face whenever I tell the story. Love the channel.

[@alanclark639]

I almost did the same - but reckon I can better your story as I was very nearly refused entry to the U.S. by immigration for the lack of a visa! My then boss had been assured we could fly visaless ( which was true then ) but to do so we needed booked return tickets - but in a typical flight of skinflinting - followed another tip to fly to NYC and pick up an internal commuter. If I hadn't known a bit about NFL and had the good fortune to meet an official the spitting image of N.Y. Giant's Lawrence Taylor - "how about that! A Brit that follows football!" He let me use his phone to buy onward tickets to Orlando from TWA whose terminal was next door and we could get there without tainting non airside soil. ( Funnily enough, in Florida they just stamped our passports.) Our D.C.9 was the last flight of the evening and was practically empty - 9 passengers with 14 crew! Lucky for me - long before security doors and after a chat with the chief trolly dolly about our route - I spent most of the trip up in the pointy end - I was even asked "are you familiar" which I still dine out on! And when I told the the crew that I'd flown a Tiger Moth - it was them that were overawed "gee! that's real flying." Mind you, a couple of days later we saw STS26 Discovery launch from the Cape so the whole trip was rather spiffing.

[@marhawkman303]

yeah, 20+ years ago I flew a few flights in the eastern US that definitely used DC-9s. Nice planes. a bit small, but quite nice.

[@TechnicalBard]

My last flight on a DC-9 was in early 2002, flying Air Canada from YYZ to DCA. As I was boarding, I found myself standing in the doorway and looked up and read the Douglas nameplate that said the airframe had been manufactured in 1968. Have since flown on MD-80s and 90s.

[@rosssmith6205]

I am retired aircraft engineer in Australia, the DC-9 was my first jet powered a/c I was licensed on. Achieved that privilege in 1971. At retirement I have 47 jet endorsements on my licence. The DC-9 is my second best favourite a/c. Great plane, easy to work on, reliable and easy to understand the systems. (except for the electrical crosstie bus system, 11 relays in series that had to operate in the correct order or you would get a crosstie lockout. Only could be rest by an engineer.) My favourite though is the Airbus A320. That is the greatest.

[@ACSFlyingfish]

Surprised to hear that the A320 is your favourite. Why so? In the airline I worked in, the engineers hated the Airbus models, they preferred Boeing. I think because Airbus wouldn't let them clear a defect if the system still self tested a fault. Whereas Boeing allowed them to easily clear tech log entries by the pilots.

[@rosssmith6205]

@@ACSFlyingfish Thanks for the reply. The 737 is so dated and costly to maintain. eg. A thrust reverser sync lock check on a 737, 5 maint. qualified personnel are required. 2 in the flt.deck, 1 in the fwd. e&e, 1 in the mid e&e and one in the wheelwell/u/c area. A320, 2 people. If a fault is detected on a 320, the on board maint. fault system (CFDS) will adsvise the engineer of not only the correct maint. procedures, but also the ref. #, revision status and safety procedures required to trouble shoot the problem. I remember when I joined Virgin Australia and was doing my 3 month training course to get my 737-700/800 license, our instructor from Alteon, the Boeing training establishment, told our course that Boeing had the best BITE (Built in test equipment) system going. He was pissed when I told him that Airbus did not use that antiquated system. The a/c could automatically check itself if asked by the engineer. I could go on, but both a/c are great, you just have to remember the 737 is a 1960's a/c. A lot of ground crew could not get their heads around Fly By Wire.An example. After Ansett collapsed in 2002, a number of ex Ansett engineers were taken on by the big Aussie airline. That airline had just started operating A330 a/c. At virgin we had one LAME on duty at all time, the other mob had at least 6/8. One day an A330 had a steering problem reported before landing. BSCU 1& 2 defect. Not only did they contact an off duty, ex Ansett LAME, but asked the Virgin LAME for help as well. (Airbus systems are very much identical between a/c types.) Ended up safely, but the guys who were Boeing transfixed were overcome with the Airbus systems. Today of course that is water under the bridge. Oz continues to have a great safety record. As for the tech log record, all Aussie maint records are on paper, in triplicate. The records are kept on file as long as the a/c remains registered in Oz. To clear a reported defect, the engineer must not only record the procedure used, the AMM chapter/subchapter/ATA ref #/ATA maint procedure number. ie ( An exterior light change for example, 34.40.601.30.) this is regardless of make or model of a/c. I will admit by the the time I retired, the paper work was getting to me. But when I started in 1964, almost all of our Captains were WW11 vets. God bless them.

[@ACSFlyingfish]

@@rosssmith6205 Thanks for your detailed reply. I understand your explanation. Tech logs seem pretty much standard with at least 3 copies made in most countries. I was type rated on the classic 737s, McDs, Fokkers, Airbus, DHC, of these I least liked flying the 737s because of the old systems and the perpetual technical issues like leaking brake reservoirs, aircond packs that couldn't produce sufficient pressurization just to name 2 that I recall from the yesteryears.

[@JohnSmith-jt5qr]

Oh, come on, the electrical system was simple. Lose a generator and the Crosstie immediately closes and puts its buses on the remaining operating generator, while simultaneously jettisoning the Galley loads. Just two Generator Buses, two engine generators, an APU, ground power (obviously only on the ground), a bunch of TRs for 28Vdc, and a battery to start the APU and operate a tiny set of loads in an emergency. Now the DC-10 was tough, and don't even get me started on the all-electric 787 which can power a small town!

[@jaminswinney6575]

I became a flight attendant for American Eagle out of DFW when I was just 19 years old (you had to be at least 19 although most airlines have a minimum age of 20) and I was usually on the ATR 72 during the dark Roselawn period. I live in Dallas and have always lived just north of downtown close to Love Field so when a company called Legend Airlines announced that it was the new Dallas Airline flying only out of Love Field instead of DFW, with a small fleet of 3 DC-9 jets I jumped at the chance and was the 3rd Flight Attendant out of about 100 finally hired . I fell in love with the DC-9 and although they were not necessarily new, ours were completely stripped of the original cabin configuration and became 2/2 with 64 seats instead of 2/3 with 90-100 seats. The concept was an all first class airline with leather recliner seats, one of the first airlines with TV’s in every seat back, designer uniforms, full inflight 3 course meal service with complimentary champagne and wine. I always bid the number 3 position so I could be in a forward jump-seat with the number 1 F/A rather than having to sit in the aft jump-seat (number 2 position) because of the noise of the engines and the terrible thought that if we had to evacuate the aircraft I’d have to use the aft cone exit that we used only for emergencies not for boarding or deplaning. I fell in love with the DC-9 and we were probably the last company that flew them exclusively from DAL to LAX, LAS, Washington DC, and LGA. Great memories of great equipment that we will probably never use commercially again.

[@rabbithutch8393]

I was a ramp agent in Lincoln, NE for TWA from '98-2000. We almost exclusively had the dc-9 md-80 variants 4-6 times a day. These were great planes to work on. We were a remote station and were trained on APU starts, engine starts and engine push-backs. I can still recall going through the APU startup procedure on a cold morning to help make it ready for the flight crew. We also had the best deep cleans on the evening shift. Bins were scrubbed, gum cleaned from carpets and galleys and bathrooms deep cleaned like new condition. The crews thought we brought them a new aircraft in the morning. I miss the days of sitting organizing the sky-mall magazines with new clean safety cards and crossing seat-belts after removing all the pretzel salt from each seat back. I still have my TWA ramp training manual and APU engine start procedure book ready to go.

[@andreas4112]

I made around 2600 flight hours as a first officer on the MD-80. It was a great aircraft to fly. A real "classic" with old instrumentation and no FMS.

[@mikej9564]

I lived 3 miles off the end of the runway in Long Beach California. As they flew directly overhead, the Boeing 727s (PSA airlines) were real screamers, while the DC9 were noticeably less noisy. I did like hearing the newly assembled DC 10s take off. They had a distinctive low whine, and of course provided many jobs to Long Beach.

[@AutonomousNavigator]

There's a small museum in the original terminal building at the Long Beach Airport. It shows all kinds of historical events that took place at the Long Beach Airport. Strangely none of the exhibits is about Douglas, which produced all its jet aircraft there. But the "Fly DC Jets" sign still stands!

[@MarinCipollina]

@@AutonomousNavigator In spite of the admittedly checkered early history of the DC 10, it remains my favorite passenger jet of all time. Nothing was more comfortable for me, more spacious or more accommodating.

[@established_on_the_run]

I’ll never forget the iconic DC-10 engine whine! You knew exactly what was flying overhead without even looking.

[@EdCali1]

In 1979 Douglas had a two page ad in Aviation Week touting "This new baby doesn't scream" and goes on to say how quiet the jet was versus its predecessors.

At one time I worked for a computer manufacturer based in Minneapolis.Flying there often involved going to Chicago and riding a DC9. My favourite memory was one time when we arrived somewhere with all the normal gates busy. Parked near a door, some passengers left using the built-in stairs. When it came to leaving the pilot used the thrust reverser to go backwards unassisted and off we went

[@jimpike7445]

As a pilot on the DC9 for Air Canada we did the reverse thrust backup off the gate for a short time but the cost savings were cancelled by the FOD (Foreign Object Damage) to the engines over time.

[@berkeleygang1834]

As a child, my first experience with the DC-9 came as a result, of meeting my sister's Godparents. Her Godfather worked for Northwest Airlines, at the maintenance facility in Minneapolis - St. Paul. He took us aboard a DC-9, and sat me in the cockpit. "Don't touch the landing gear handle!" (as if it wasn't pinned). I also remember going through the engine shop, where I marveled at the clam-shell thrust reverser. In my professional career, I flew many times on DC-9s and it's variants. I can't say it was my favorite airliner, but who can forget those PSA DC-9s with the big smile painted on their fuselage? I also was involved in evaluating proposals for the US Navy P-3 replacement (Long Range Air Anti-submarine Warfare Capable Aircraft, LRAACA), which included a MD-80 variant with unducted fan engines, the P-9,; a designation clearly giving homage to it's DC-9 roots.

Twin engine aircraft are by definition over-powered so that they can successfully climb if one engine should fail at take-off.

[@slartybarfastb3648]

@StefanMochnacki The DC-9-20 Took that principle pretty far though. It had the JT-8D-200 series engine which was intended for the stretched 30-50 series of DC-9, but used on the shorter -20 as well.

1974 first airplane ride. Delta DC-9 from Atlanta to Miami. They used to call the Delta version the Snoopy because the front with its black 'nose' resembled Snoopy's head.

[@jamesfirnhaber984]

I flew the DC9 as both FO and Captain. I always told my FO, "I am the FMC." Probably my most memorable DC9 experience (among many) was on a flight between MSP and Toronto. Approaching Toronto we were cleared to an NDB to hold on an NDB radial. It was nighttime and we were in the clouds with an 80 knot crosswind to our holding radial. By the time we figured out the correct crosswind heading to maintain the radial, we were cleared out of holding. The DC9 was a very physical airplane to fly. It may have been the first commercial aircraft with an integrated master caution/warning system. It was fun to actually pilot, but exhausting after the fourth or fifth leg. My favorite variant was the -30 with -15 engines. Still can't believe we used reverse thrust (where allowed) to back out of our gates. One other note- it had to have the most complex cockpit window closing mechanism of any aircraft in history.

[@ricksmail777]

I have a soft spot in my heart for the DC-9 as it was the first jet I piloted. My relationship started as a passenger in 1967 flying on a TWA DC-9 from PIT to STL to attend collage. In 1977 I upgraded from being a 727 Flight Engineer to DC-9 First Officer. What a thrill it was for me as all of my previous experience was flying prop aircraft. The biggest short coming of the DC-9 for me was the lack of ground cooling for the cockpit. On hot days we would open the cockpit windows when taxiing and waiting for takeoff and close the outflow valve (the valve in the back of the plane that controls cabin pressurization by opening and closing) so all the air-conditioned air would flow out of the plane through the cockpit windows. When you did that you had better make sure the outflow valve was open before closing the cockpit windows!! This was the only way to keep cool in the southern cities we served. I only flew the DC-9 for about a year when I moved to the right seat of the 727. After the 727 I few the 757, 767, and ended on the 777 but the DC-9 will always be my first!!

[@MikeJamesMedia]

I love these videos, because I'm in my late 60s, and grew up transitioning from airliners like the DC-3, DC-7s, Constellations, etc., to the DC-9s, 727s, 737s, and the 707. It was striking (putting it mildly!) to make a flight in a DC-3 at 8000 feet, then switch to a jet, and travel at 30,000 feet, and three times faster.) :)

[@erniepyles]

I used to work on dc-9s as a young A&P mechanic, absolutely love them, easy to work on you can reach everything under the wing simple controls easy Avionics, just easy access for everything

[@LandNfan]

I loved the “Dizzy 9.” It once led to me flying part of a trip in first class by pure luck. I was flying from EVV to BOS with a connection in PIT. It was when airlines started experimenting with giving all your boarding passes at your first check-in. The EVV ticket agent asked if I had a seat preference and I asked for an aisle seat forward. She checked her screen and and said you can have 3B. After a further look she said you can have 3B on both flights. When I boarded the plane was a DC-9 and was configured as all one class. Where the story gets interesting is the connection in PIT. It was supposed to be 2 hour connection, which was OK because it gave me time for an unhurried dinner. The weather in Pittsburgh was wretched, with heavy thunderstorms. Planes were delayed both in and outbound. My 1900 departure finally boarded at 2200. When I stepped onto the plane, it turned out to be a 727 with seat 3B in first class. I sat down and the FA said, “would you like something to drink?” I replied, “I wouldn’t mind shaking hands with Jack Daniels.” The head FA kept came forward three times muttering about 93 in the back and 6 in the front. At one point the first class attendant asked to see my boarding pass. Seeing the 3B assignment she asked if I would like another Jack Daniels. Finally the head FA said 93 in the back, 6 in the front, we’ve got our 99, let’s go. So I got to enjoy the flight to BOS in the relative luxury of USAir first class.

[@georgedyson9754]

In the early 1970's I flew many times on Air Canada DC-9s. I really loved them as they were the most common aircraft within Canada at that time and they just seemed to fly so well. In many smaller airports at that time, there were no gates that the aircraft pulled right up to, and instead the internal ladder was dropped and we all went down that and walked across the tarmac to the terminal - often in subzero temperatures. It was indeed very refreshing to start out of the warm plane and be attacked by sub-zero winds as one went down the stairs until one could scurry into the terminal Nothing like a drop in temperature from plus 20C to minus 25C!

[@FrewstonBooks]

Done the same many times - Sudbury at -25C taking off in a snowstorm bouncing from 'snowdune' to 'snowdune'.

My dad flew the DC-9, MD-80 and MD-90 in the past. As an 80s airline brat I was lucky enough to sit on the jump seat many times, and even got to fly the DC-9 simulator SAS had in Stockholm. Long live the legendary DC-9 and thanks for the video!

@Petter, super, super thanks so much for doing this story. For us living in Norway (Bergen), the DC9 and the following MD-8x, MD-9x series was the benchmark of aviation for decades, flying with SAS between Bergen and Oslo. I loved, loved, loved flying the DC9 ❤💙💛 I reckon that insanely steep takeoff angle is unprecedented in any other airplanes. Actually, I even miss the DC9 today 💔🥲

[@rtundlt1]

I have about 10,000 hours in the mighty DC-9 as both First Officer and Captain at Northwest Airlines. I flew the -10, -30, -40 and -50 series and they were great airplanes. From the doorway the cockpit looked cramped but once you climbed in and got in your seat it was very spacious and comfortable, as long as being cool in the summer wasn't a requirement. Very rarely did it leave us stranded and that was quite remarkable for an airplane with some very complicated solutions for simple problems. For instance, the circuit breaker for the battery bus was on the forward bulkhead just behind the radome. To reset that breaker there was a BATT BUS reset lever on the aft of the center pedestal that was connected to a small cable that ran through conduit and around pulleys that would pull up on a metal flap with a bolt in it. When you pulled the reset lever the cable would pull up the metal flap and the bolt head would push the circuit breaker in. It was an awesome aircraft and a real pleasure to fly. Boeing built airplanes, Douglas built character.

[@cjdelmege2939]

BA evaluated the 737/DC9 in the late 70s. The DC 9 was a bit faster and definitely better built but they still went for the 737.

[@flaps45]

Towards the end of the DC-9’s passenger service in the US, it was a minor hassle for air traffic control. Because it didn’t have GPS or as modern an FMS navigation system, it would not hold course as precisely as newer aircraft. GPS equipped airliners fly a straight line right down the center of an airway; older aircraft like the DC-9 using VOR navigation tend to wander back and forth very slightly, essentially making a shallow zig-zag down an airway (Victor airways in the US are 8nm wide). Back in the day when all aircraft did that, it wasn’t a problem. But when you have a GPS airliner right behind a DC-9 at the same speed, you will slowly lose separation since one aircraft is flying a straight line and the other is zig-zagging slightly. In busy airspace, that can be an issue. A friend of mine is an ATC center controller, and I remember him telling me back then, if he had a DC-9 and something newer side by side and he had to pick one to sequence first, he’d always put the DC-9 in the back of the line to avoid separation issues.

[@DaveNLR2]

I used to fly the DC-9 on Ozark Airlines from MKE to ORD to plane spot and listen to ATC on a portable radio when I was 16 yrs old. I usually flew down on a Fairchild twin-prop and flew back on a DC-9. It was so much fun, and the round trip ticket cost $25... Which I earned by delivering newspapers (remember those?). Great video. Seeing that clip of Ozark Airlines brought back so many memories. I love the DC9 and all twin engine rear mounted jets like the CRJ. May their rocket take-offs live forever.

[@michaelmorrison6540]

Decades ago (in the 1970s and 1980s), Continental Airlines had a major presence at both airports in Houston, Texas - Houston International (north side of the city) and Hobby Airport (south side of the city). Continental would connect passengers between the two airports with an hourly shuttle service using DC-9s (-10 series). As the distance between the 2 airports is only about 25 miles (40 kilometers), the flight time was very brief (about 12 minutes from takeoff to landing). Furthermore, those DC-9s flew unpressurized as their “cruise altitude” was between 3,000 feet to 5,000 feet (914 meters to 1,524 meters) above sea level. I was a DC-9 mechanic/engineer for Continental Airlines back in the 1980s at Houston Hobby Airport.

[@andersonnettleship845]

Another great and informative video and I loved flying on the DC-9 and the Mad Dogs and 717s but by far my favorite airliner is the Convair 580 which is a Turboprop Conversion of either a CV-340 or CV-440 utilizing a pair of Allison 501d-13 or 501d-13h turboprops with 13’6” Aeroproducts Square Tipped 4 Blade Propellers! This was a very similar engine/prop package used on the Lockheed C-130 (Allison T-56) with the reduction gearbox mounted above the engine as opposed to below and with the engines derated to “only” 3,750 SHP with an additional 800lbs of jet thrust. The Lockheed 188 Electra 2 and P-3 Orion also used the same powerplant. The Convairliners series was an important and influential aircraft in its own way and deserves its own episode on your fantastic channel, several aircraft are still flying and earning their keep including 6 C-131 aircraft that have been “stretched” to produce the Convair 5800!

They wanted large passenger capacity with the wide mainliner fuselage, they wanted light weight and more capacity with wing mounted engines, and they wanted the fuselage low to the ground for easy servicing and on-board airstair--decisions that curse them to this day and indeed throughout the history of the 737 (fuselage structural problems, original thrust reversers lifting the plane off the runway). The DC-9 did have the disadvantage of fuselage mounted engines which means either higher weight (as the wing attachments have to carry both the fuselage and the engines) or a lower zero fuel weight, but this meant that it could easily be stretched to insane proportions like the MD-90 by stretching the fuselage forward of the wing and adding larger and heavier engines behind it to balance it out. Another small disadvantage of the DC-9 was its narrower fuselage... which reduces ultimate passenger and baggage capacity (particularly overhead bin space) and makes boarding and disembarking more tedious. The near perfectly sized single aisle plane was introduced in 1967: the 727-200. 189 passengers maximum. This captured the lions share of 727 sales and defined domestic mainline operations in the US. Boeing couldn't modernize the 727 because of the tail mounted engine. Three engines was too much and there was no way to eliminate the second engine. So Boeing designed the 757 to replace it. They made it slightly larger to be more profitable, and they built a lot of growth into it to prevent the headaches they had with all of their other narrow body airliners. But.. it was too big.. and with deregulation and the transition from hub and spoke to point to point travel, it didn't make any sense. And for long haul passengers prefer wide body aircraft. So when it came time for Airbus to enter the single aisle market, they took square aim at the 727. The only major things they changed was the number of engines, and any requirement to do regional flying at unserviced airports. They could make it a little bigger into the A321 to make inroads against the 757, and a bit smaller to compete with the 737 Boeing had no choice. It had to stretch the 737 into the -400 to compete. It had to stretch the NG into the awkward and poor selling -900 to compete against the 321 as the 757 line was shut down. What's interesting is that Boeing kept the 717 alive as a regional airliner after the merger.. since it was smaller than the 737-600 which was a poor seller because like the 757 it was too huge for the capacity. But the 717 didn't sell much either and Boeing was shutting down Long Beach and legacy MD products save the lucrative C-17 orders. Regional airlines were gobbling up CRJs and ERJs as smaller cheaper jets. But both the airlines and the travelling public desired something larger so we got into the five across E-Jets and C-Series. One wonders what would have happened if the 717 was redeveloped and modernized as it would have been the perfect size--scope clauses notwithstanding. Flying in a 717 is heaven compared to a CRJ.

[@marcmcreynolds2827]

Interesting points. My quibble list: 727 ended production years before the A320 entered service, so maybe you mean the A320 was aimed squarely at the sort of use airlines had made of the 727? Overhead bins on an MD-80 had to have a depth comparable to the competition or allowable-length carry-ons couldn't fit wheels-first (not that today's wheeled bags existed yet). So five people instead of six vying for about the same volume. The offset aisle could make for a slightly unbalanced walking experience, however. To my way of thinking, the 717 already represented "redeveloped and modernized" to the extent it could be thought of as a DC-9-30 update. FWIW, I see the 757 as more of a 707 replacement, especially the earlier 707s which couldn't match a DC-8 (hence the 707-320). But as you note, it was sort of a tweener.

You showed up at the airport without a reservation, walked to the gate (no security back then), filled out a card, walked out onto the tarmac, put your bag on the baggage cart, and boarded the plane. In flight, the drinks cart came down the aisle, but it didn't have drinks - it had the credit card machine. You hadn't purchased a ticket yet. Super efficient.

[@philipgrice1026]

Before retiring seven years ago I had over 40 years flying commercial aircraft as a passenger. I am also an FAA licensed pilot for GA aircraft having owned one myself for some years. There is no doubt in my mind that I preferred the DC9 family of aircraft over the 737 family. The DC was smoother flying, quieter and , from my experiences, more reliable. On the other hand, giver my annual air miles exceeded 100,000 most years, I also experience a total of seven unscheduled landings. Three in the DC8, two in 707s, one IL72 (a Soviet copy of the DC8) and one 727. I have to say that only the DC8 unscheduled landings were scary, each being the result of loss of power on the flight deck in all three cases! Losing an engine, even when they explode or fall off, is not as traumatic as the aircrew not being able to see their instruments at night, in bad weather and without radio communication to air traffic control. But given a choice for short haul flights, I'd always choose a DC9 variant. The only design flaw was with the air-conditioning, which was powered from the JT8Ds, and turned off(!) when taking off or landing, just when all the Alitalia passengers were exuding the maximum amount of garlic from their sweat pores.

[@thomasm1964]

I swear SAS pilots flying these aircraft out of Oslo were training for a top secret Norwegian space programme. I have flown out of Oslo twice. On both occasions, we went up like a rocket and banked so sharply that we tracked back parallel to the runway from which we had just taken off! My first experience with the DC9, though, was with Cyprus Air in 1976 just after the punch-up of 1974. As RAF Akrotiri was about 100 miles away on poor roads my parents decided I should fly Cyprus Air to Larnaca rather than the RAF to Akrotiri. Larnaca was only about 15 miles or so from Dhekelia where we lived. At the time, Nicosia had been the only commercial airport for Cyprus but had been abandoned following the war. It is still abandoned. Larnaca was then a general aviation airfield but had been pressed into service to replace Nicosia. To say it was basic would be an understatement. Anyway, Cyprus Air had no maintenance facilities in Cyprus so they had to use Heathrow and hope for the best if problems developed en route. On my flight, we lost an engine about an hour out of Cyprus. I don't know what the pilots were facing in terms of other potential problems but I remember we came in very hard and fast. The aircraft slammed into the runway bounced three times and raced off the end of the runway into bushland where it eventually came to s stop. After about 30 minutes, a fleet of tractors arrived from nearby farms to haul the aircraft back. How they managed it I do not know but they got the aircraft back onto the tarmac and it was able to make its way to the terminal under its own power. My parents were watching all this from the viewing balcony on top of the terminal building. They saw Number 1 son merrily careering down the runway, hopping and skipping as he went and then watched the whole recovery operation unfold. Needless to say, my Mum put her foot down with a firm hand and I always flew RAF after that, necessitating a 200 mile round road trip for my poor Dad! The world was a different place back then!

[@AutonomousNavigator]

Douglas developed the DC-9 during a high inflationary period, and took many orders at a fixed price years before delivery. As Douglas's production costs increased, the strong orders stretched cash flow, and led Douglas to seek a buyer. McDonnell Aircraft had only government contracts during the space race and the Vietnam War, on either a cost-plus basis, or fixed price with short time horizons, which led to ballooning profits in an inflationary environment, giving them excess cash flow to acquire Douglas. And US government tax policy led to the development of the 707. The government imposed a "war profiteer" tax during the Korean War, and because at the time Boeing was almost completely a government contractor, it's profits were much more exposed to the "war profiteer" tax than competitors like Douglas, Lockheed and Convair. Because R&D was a tax shield, developing the 707 reduced Boeing's exposure to the tax in ways that weren't available to its competitors.

[@jsfbr]

The most striking DC-9's feature I noticed is that its engines are installed pointing slightly upward. I had some trouble understanding this, as such configuration would induce a huge, parasite down-pitch momentum, with a cascade of undesirable consequences. I found the answer on the Internet some time later. The engines are so installed so as to properly align them with the airflow "bent downward" by the wings' upper surfaces. To compensate for this, the engines' exhausts are "bent upward" by the engines' cowlings, thus avoiding the down-pitch. Clever!

[@davidpowell3347]

I think they were trying to make it pitch change neutral when engine power is changed either up or down.

[@jok.310]

They are very quiet while sitting in the front cabin. You can almost not hear the engine during take off. Onle the wheels! That is an amazing feeling

Never had the pleasure of flying the DC (for Direct Cable...haha) 9, but I rode jumpseat on it a lot. Ours were super basic. VOR navigation and a really rudimentary autopilot. Compared to our 737s and Airbuses, it was practically archaic. I asked one captain of a flight I was jumpseating on if he liked it. He said that he did. I asked him what he liked about it and he said, "If I crash in this thing, at least I'll know why!" He had a point; there's something to be said for old school flying.

[@danbenson7587]

Looking over Mentours vids, when an event happens on contemporary planes, the pilots are surprised, and confused. They have to immediately think through all the interlocking layers of automation. Try that with a warning horn blaring. There’s something to be said of old school because it kept the pilot engaged. As an aside I had experience reading machine pressure both with a “steam” gage and digital simultaneously. The steam gage provided a visual sense of rate of pressure rise/loss. Extending this to glass cockpits ..automation and side sticks deprive the pilots of sensory information.

[@paulw4310]

@@danbenson7587 Agreed. With that said, technology can be a wonderful thing and can greatly reduce a pilot's workload...as long as it's working. Over-reliance on technology, however, is a bad thing and has proven far more than once to be fatal. There are too many accident reports that show both pilots working a problem with the automation...while leaving the automation engaged. If automation is the problem, turn it off! The pilot flying needs to hand-fly, wings level, pitch and power to prevent exceedance of the critical angle of attack while respecting terrain. It's the pilot monitoring's job to work the problem. So many catastrophic accidents could've easily been prevented if one pilot just disconnected from automation and aviated while the other pilot did the troubleshooting. PS You're right. While some aural warnings can't be canceled until whatever is causing them is rectified, very often the aural caution and/or warnings alerts keep blaring away causing a great distraction. Once whatever is causing them to sound is ascertained, they should always be immediately canceled to prevent undue distraction.

TAA (now Qantas domestic) flew DC9s. My first DC9 flight was to Launceston in Tasmania, where the terminal is half-way along the runway. TAA pilots had worked out that, if they touched down near the very start of the runway, slammed down the nose and hit the brakes hard, they could stop in half the runway length and turn straight into the terminal! Their competitor's 737s needed more runway and had to taxi back to the terminal.

The flying boom refueling system was developed by Boeing and was why it was the only contender for the jet tanker program. The commercial potential of the design led to the 707. With the transcontinental/intercontinental 707/720 launched, Boeing turned to the next market sector which was around 100pax, medium haul, smaller airports. This was the 727 with three JT8Ds. Douglas judged that market was not big enough for two aircraft (no one took the Trident seriously) so it went down to the next sector - a short haul jet with two JT8Ds. Boeing was fully committed with the 707/727/C-135 and decided to wait before entering that sector. It was a little crowded with the BAC 1-11 and the Caravelle. The rightness of the decision to go with the DC-9 can be seen in all the airlines that opted for a 727/DC-9 mix. Match made in heaven. When Boeing decided to join the fray it decided to make its aircraft different from the five abreast, rear engined competition. The 737 would be six abreast with the engines under the wing. That was the future although Boeing's desire to keep the floor height the same as the 727 has been the 737's weak point. Too many compromises have had to be made to fit later engines under the wing that the A320 has never had to make. In hindsight Boeing should have replaced the 737-200 with a shortened 757 fuselage/cockpit, new wing and pylon mounted CFM56s. But has to be admitted Boeing was heavily committed to the 757 and 767 programs and probably did not have the resources. The 737-300 was four years before the A320. Things might have been different if Boeing has waited two more years and used the 757 fuselage/cockpit as the starting point for a 737 replacement.

I flew on an original DC-9 only once, but had a few flights on various MD-80s and even 717s. When I had the chance to be on a DC-9 in the second half of the 2000s, it was clear that I had to sit all the way in the back to enjoy the JT8D sound, and enjoying it I did. I also link this aircraft family (at least before the MD-87) to a few very unique sounds, much like today the "barking dog in the cargo hold" PTU sound is something iconic for the A320 family. For one, every time the PA came on, there was this 400 Hz sound overlayed, likely because filtering of the AC power wasn't nearly as good back then. And also when the engines were started up, you could hear the ignition capacitors charge through the PA speakers. Something I have never heard anywhere else. (Some other aircraft had the 400 Hz tone, but not as pronounced as the DC-9s)

Was just in the US last month and now recall seeing Air Canada MD-80s in both St Louis and Washington DC. The DC-9 in all its incarnations lives on!

Growing up in Scotland in the 1970's, we predominantly took package holidays to Europe with some sort of charter from Glasgow. More often than not, those were Britannia 737-200's to the Spanish mainland and islands. It's a type I still love - there's not nearly enough on KZbin about what the Jurassic's did apart from the last few survivors soldiering on for Canadian gravel runways. But now and then we would get a surprise, one Spanish trip we had an Aviaco DC-8 which seemed impossibly huge. In the early eighties we switched our holidays to Yugoslavia and those flights are almost exclusively on Inex Adria DC9's of a similar vintage. It may well have been down to their predominately ex-military crews, but they always felt like sports cars compared to the short stubby Boeings.

And then subsequently, the DC-9 became the "anyways, here's Wonderwall" of planes.

1996 first aircraft I ever flew on was a Northwest Airlines MD-80. That was quite the experience sitting near those engines and hearing them spool up.

[@dmacpher]

de Havilland Canada DHC-6 Twin Otter 😆 It’s now being built in Calgary again. First plane went into service in 1965

[@svenarneekse]

I was an ICAO licence engineer on the DC9 - MD 80 serie and is amazed of the simplicity and well done construction of this a/c. I also had license on the B737- 200- 900 and this was a more clomsy and heavy a/c. A clear thumb up for the DC 9 👍

[@chemiker494]

Yes, the DC-9 was the first airliner I flew in as a passenger, and leaving it through the rear eit felt really cool

[@grahamschurman6796]

My first flight was in an Air Canada DC-9 in 1971, when I was 11 years old. Air Canada had a promotion in which for a nominal fee, teachers and students in Montreal-area schools were offered flights from Dorval of about half an hour. It was a great thrill, and I still think the DC-9 is one of the best-looking aircraft ever built. I have a black-and-white photo taken that day of the aircraft we flew on and it looks great. I still have good feelings toward Air Canada for doing that.

[@TheRatsCats]

My first flight was approximately 1973 or 1974, from YSB to YYZ. It was so impressive for young me. I've always had a warm feeling for the DC9 since then.

[@paologiuliopedroni1831]

I flew on SAS MD-80 and MD-90 in the 80s, when I was an ERASMUS student in Luleå. I loved that plane: as long as you didn't sit in the back it was really, really quiet.

[@living4christ]

I flew on a delta dc-9 when I was a kid, 7 years old as an unaccompanied minor from ORD to MSY. That sparked my interest in aviation. I will never forget that flight.

[@alasdairmackenzie905]

My first ever jet flight was on a KLM DC9 in around 1968 and I can still remember being absolutely amazed at the initial rate of climb immediately after rotation. Beautiful aircraft and so much quieter inside (thanks to the rear engines) than the contemporary 737-200

[@XRP747E]

I flew the 'nine' for the first in 1979. The model that was very agile and sensitive on the controls was the 10 series. I well remember my surprise at the performance and the way it felt the first time I flew it. A little rocket. I was lucky enough to spend 11 years on this beautiful aircraft (10 and 30 series). I really enjoyed this video. Thank you, Petter!

[@ullahelwegrothe2024]

Yes..❤ My favorite is still the Sterling Airways SE210 Caravelle 12 ❤ the most elegant french bird from my childhood .( 5 - 14 years old) So noisy a cabin, but I remember her standing there in Verona Airport 1970- 80 .flying us back home to Copenhagen Her elegant wing and fuselage and windows and STERLING AIRWAYS coulour❤ .. I cry every time I see a Caravelle..I remember all the vacations at Lake Garda with my mother .

[@svenmorgenstern9506]

Flew the DC-9 a few times in the late 1960's & early 1970's, when Air West (regional West Coast airline, later became Hughes AirWest) was in operation. Two things I remembered distinctly; first was using the lavatory, which was interesting because on those particular aircraft they were located just about even with the engine pylons. You got a full dose of the JT-8D singing the song of its people at full volume. 😮 Second was when my mom & I were flying up to southern Oregon, and we were scheduled to stop at Eureka/Arcata airport on the California coast. It's still there and I doubt it's been modified much since 1970 or so. Only time I've ever assumed crash position on an aircraft - fully loaded DC-9 & an airport who's main runway is 6,000 feet long. Minimum runway length for the DC-9 was 5,900 feet. Pilot planted that plane on the runway & went full thrust reversers/air brakes/wheel brakes & if he'd had a drogue chute I'm certain he'd have used it. The plane was shuddering like it was having a seizure, passengers were praying...and 7 year old me tried to look out the window (mom stuffed my face back down in the pillow). I was able to look out to see the starboard wing sticking out over the boundary fence when it finally stopped, and the passengers were cheering & applauding. We offloaded about 20% of the passengers there (they got travel vouchers) & the rest of us took off for Jackson County airport. Good times. 👍

[@marcmcreynolds2827]

FWIW Orange County (SNA) main runway length, where Hughes Airwest operated DC-9-30s for years, was and still is 5700 feet.

[@feishida]

I recall flying in DC-9s with Swissair, and later in their MD-80 versions with Northwest, TWA and American. Always loved its design and comfort. (BTW also flew in the Caravelle - Air France - and Boeing 720 - United; as well as the Convair 990 -Swissair … way back when)

[@jmclaugh]

My first job out of college was in DC-9 Aerodynamics at Douglas Long Beach. We were creating CFD wire frame models for stretched variants of the MD-80, which went into service the year before I started. I flew on Muse Air MD-80s many times. It was a great aircraft!

[@Buzzkill-wn7tf]

As a kid who grew up under the flight path for the main runway landings in my little city, I can still remember the engine sound of the DC-8, DC-9 and 727 (holy hell, was the 727 loud). But I always loved the lines of a DC-9! Flew on it once or twice and loved every second!

[@established_on_the_run]

The 727 was SO loud. A screamer!

[@TuomasLeone]

Many a great memories for me, on FINNAIR Caravelles and DC-9s. As kid we'd travel from the US to Finland just about every summer, I always hoped we'd get a Caravelle on our flights up north into Finland, as I really liked it's look with those triangle shaped windows. That and in the early days, the other option was the Convair which I despised. As they began to be replaced by the DC-9s I sure did miss them. Hopefully you can do a deep dive on the Caravelle on day.

[@57Jimmy]

My very first airline flight was in 1975 Air Canada DC-9. Regina to Vancouver. I was scared beyond measure! 16yrs old, all alone. NEVER been on a jet! That shear terror left just as quick as it became airborne! That 2.5hr flight left a lasting impression equal to the impression of my face being stuck to the window taking in all the beautiful sights! Also the first time seeing the planes shadow below in a halo of colour flying through the thin clouds! I loved it!

[@rkc62]

The DC-9 will always hold a special place in my heart as it was the first jet I ever flew on, from Sydney to Brisbane, and I was the only person at school or in my social circles who had ever flown on a jet. It was so exciting, whereas now every time I realise I will have to fly there is a sense of it being a chore.

[@Kosahdus]

Good memory of sitting on jumpseat at cockpit and Captain remembered that now is spring in departure destination and opened the window to cooldown cockpit. He closed that just before lineup to runway. And whole taxi he had his elbow out of window 😎

[@MayorMcCheese47]

Im an A&P working at my local airport and a few months back saw an Ameristar cargo DC9 taxi to our FBO ramp. It was a 1966 built aircraft, still in service in 2024. They are close to 60 yrs in service!!

[@Ivehadenuff]

I flew on the DC9 for years as a flight attendant. I remember the tail cone exits. Haven’t thought of this plane in a long time.
