The DC-9 Story - Part 1: The Douglas DC-9

Greetings! :D
In this two part series, we'll be looking at an airliner so successful that it nearly bankrupted its parent firm, the Douglas DC-9, having crawled its way from a proposed model with no commercial interest at the beginning of the 1960s, becoming one of the most popular short to medium range airliner models by the end of the same decade, having fought off the BAC 1-11 and even given Boeing a run for their money, and from its phenomenal rise would spawn its own successive generations of twinjets that would see work into the 1980s and 90s.

I flew on one of these just last week, well kinda; it was a B717 (Qantas, Sydney to Hobart return). Flying the B717 on one of the few carriers in the US & Australia who still have them in their fleet is probably the nearest you'll probably get to experience a commercial passenger flight on a DC-9 in 2023.

[@geminian7846]

I flew on a genuine DC9 on an internal flight in Venezuela in 1999. Looking at the 'boiler plate' on the door post as I boarded, I saw that it was already 31 years old. As they started up, the engines sounded as if they hadn't ever been serviced. But it got me there, and back.

The DC9 and the MD80 are probably the type of plane I've had the most air time with as a passenger, seeing my parents lived in different parts of the country and it was more or less the default jet for regional domestic flights in Sweden during the eighties and nineties.

The MD80 is one of the smoothest commercial jets I’ve ever flown on while in turbulent air. Also, one of the quietest and that was in the 90’s! My favorite seat, just forward the jet engine’s intake, which also offers a good view of the wing surfaces.

I had the good fortune to ride on a series of rear-engined airliners and I agree about the quiet cabin. My first flight was aboard an Air France Caravelle, and I then went on to multiple flights on BAC 1-!!, VC-10, DC-9 and MD-80 (most of the latter being flown by Swissair or SAS).

I've made so many flights on MD80's and DC9's. It's a shame that COVID accelerated their retirement. I mostly rode on AA MD80's. Many of these were taken over from TWA. I distinctly remember flying on a Spirit Air DC9 that was configured single class. It reminded me of a bus or a train! I hear the pilots considered it a fairly hot plane. It has high wing loading compared to the 737, so I guess it feels more like a fighter jet when you turn and climb. These were fun planes to ride on too.

You missed the 1996 crash of a ValueJet DC-9 On May 11, 1996, ValuJet suffered its highest-profile accident when Flight 592, a DC-9 flying from Miami to Atlanta, crashed into the Florida Everglades, killing all 110 people on board. The crash was caused by an onboard fire triggered by full chemical oxygen generators that were illegally stowed in the cargo hold without their safety caps, by maintenance subcontractor SabreTech. The resulting investigation revealed numerous systemic flaws, and ultimately faulted both SabreTech for storing the generators on the plane along with ValuJet for not supervising them.

[@jonathankleinow2073]

ValuJet, and later AirTran, really ran their DC-9 fleet ragged, and each had a few accidents without any fatalities. ValuJet was to be the launch customer for the Boeing 717 (or the MD-95 or even DC-9-95 if you're so inclined). A lot of people assume ValuJet shut down after the Everglades crash, but they actually bought and merged with AirTran in order to obtain a new identity, if you will. I will say that, by the time Southwest bought AirTran in 2011, they had a very modern fleet of 717s and 737s. Delta bought and refurbished their 717 fleet from Southwest and plans to fly them until 2025.

In 1977 I flew on a DC-9 from DFW to Austin, TX. It was a Texas Iinternational (?) plane. We had 2 stops, one in Amarillo, the other in Lubbock. On approach to Amarillo the pilot went into a dust storm about 1k feet from the ground. The wind was wicked and I thought he was going into a flat spin and we would pancake into the ground, but we didn't. At the gate the plane rocked back and forth like I have never experienced before. I have another story when were in a DC-9 taking off in a dust storm in Chihuahua. It was screaming passengers holding onto their rosaries all the way to Juarez it was so rough. The pilot made an almost 90 degree turn as we lifted off the runway in Chihuahua. I was on the port side looking out the window. I thought the wing was going to scrape the ground. Oh, well; it was better than driving. :) We kissed the ground in Juarez. We all lived to fly another day in a DC-9, hooray!

[@tomellingham8627]

The Comet was a trail blazer, and unfortunately, the manufacturer and the aircraft ended up paying the higher cost for being a leader, not a follower. All proposed jet engined windows were designed square before De Havilland worked out - after hugely expensive scientific investigation - that a square window design in a pressurised aircraft can lead to structural failure. An oval windowed design is the safer solution. The Comet makers re-engineered the Comet and shared all their lessons-learned with the entire airliner manufacturing industry for the benefit of everybody. It cost them dearly. Other manufacturers could learn from the experience of the world's first jetliner, saving a fortune in R+D, and reap the benefits in the order books, free from the stigma of negative publicity associated with the pioneering aircraft design. Nontheless, the redesigned classic Comets that flew proved in the end to be fantastically rugged and reliable aircraft that served operators well into the late 20th century. Considering it was the world's first jet airliner, it was a success. Whenever we make a routine flight aboard a comfortable, modern pressurised 320, 737, or 321, we fly in technology with roots in the pioneering Comet design. History can be however we like to tell it - but it's always best if history represents the truth. And the Comet was also, as you say, a beautiful aircraft.

[@tomellingham8627]

My previous comment underestimated the longevity of the Comet somewhat. 😄 I forgot that the Nimrod - for a long time an integral part of NATO air defence, as well as an undisputedly valuable search and rescue tool - even surviving intact after a sea ditching in the late 90s. The Nimrod served daily missions every day into the 2010s. It's easy to forget - as I just did - the Nimrod was none other than a military versioned Comet.

I liked the Boeing 727 because of the higher performance. The DC9 should have been the basis of Douglas financial recovery. The problem was mismanagement.

[@Colaholiker]

As far as I know, the 737 is not widened compared to the 707 and 727. The cross-section is the same and all of them had 6-abreast economy class seating. Even the 757 re-used the same cross-section as far as I know. (which basically means that all Boeing passenger narrowbody jets have the same cross-section, apart from the 717, which is just another step in the DC-9 evolution and thus not an original Boeing design). The only widening that I am aware of is between the -80 prototype (and the KC-135, which shares the fuselage cross-section) and the 707.

Note that the DC-9 was responsible for taking out another manufacturer’s aircraft McDonnel Douglas made a habit of that including taking out Concord with the DC-10 and now they are doing the exact same thing as they are now part of Boeing. They are a considerable health and safety hazard.

[@johnyoung1128]

“Taking out Concorde” utterly ridiculous. That’s about as big a blame stretch as I’ve ever heard. The part that caused the Concorde tyre failure was from the GE CF6 engine of a DC 10, in other words a part NOT designed or made by McDonnell Douglas.

[@toomanyuserids]

The DC-8 was always a great ride, tho $24 first class Braniff SFO-LAX 707 first leg to LatAm was sweet. The DC-9/MD-80 was also generally nice. I loathe the 737. I avoid it when possible. The seat layout on most carriers best described as 'chunk light tuna'. And it's been stretched way beyond any sanity. Give me Airbus. Better still, Embraer.

[@uncbadguy]

Douglas always built great airplanes. I regret never getting a ride on a C-47/DC-3.

[@tbusman1]

Where is part two at?

[@Sacto1654]

In my opinion, the DC-9 had the real misfortune of arriving at a time of declining sales of the DC-8 and the expensive safety issues the plagued the DC-10. And sales got really hurt with the 737 Classic models with the CFM56 engines arrived in the 1980's.

[@bagelish6686]

Actually the DC-9 arrived well ahead of any DC-10 safety issues. Only the series 50 was post DC-10. Also, the DC-9 was outselling the 737 in the late ‘60s, with deliveries exceeding 200 per year. Unheard of in those days. Douglas miscalculated the production logistics, cost, and sales volume. It was a victim of its own success.

That very last scene of the aircraft landing and breaking its tail… tell us more please!

[@heidirabenau511]

It's a crash test for certification.

[@macjim]

@@heidirabenau511 ah! Thank you for that information.

[@TheUglyGnome]

@@heidirabenau511 Not a crash test. A landing distance test.May 2, 1980. MD-80. Excessive sink rate and pilot's inability to correct it resulted in very hard landing. One flight-test engineer injured.

[@crazygood150]

Fun fact, it was actually rebuilt and flown after that!

[@marcmcreynolds2827]

Sink rate at touchdown was about 16 fps, vs the MLG's design failure rate of 15 fps, so at least the gear went above and beyond (perhaps helped by the tail coming off for load relief : ) The test card called for no trajectory adjustments below 100 ft, but the (FAA?) pilot decided they could finesse things and save a go-around. In the original 16 mm film you could see the fuselage noticeably bend for a film frame or two, and the tail get dragged along on the runway by control cables for maybe a second or less until those broke as well.

[@huwzebediahthomas9193]

A concept - very regional 30 seater with two radial engines, modern?

[@stanislavkavale4813]

...spot the error at 21.32, Czech Islands???? c'mon man! we don't even have a coastline.

[@thomasburke7995]

Ok some technical errors.. the DC-9 was not in direct competition with the 727. 737-200/300 was a direct competitor to all varieties of the dc/MD line. The DC8 was not a failure , the engines required to meet performance were not developed untill the late 80's. Delta is still operating the MD-90 (DC'9-900) and DC-8 was used by United as late as the early 90's.

[@medic_gamnig_savetf2]

Information: DC 9 is Turkish Airlines' first jet plane.

[@icarus_falling]

What's the story behind the tail breaking off the aircraft at the 24:50 mark?

[@Part_121]

Not sure about that one, but when I worked at Eastern Airlines, we had one crack in half on landing in Pensacola, FL, sometime in the late 80s. Luckily no one was killed, but 3 people were injured.

[@johnyoung1128]

Its a MD80 that had an excessively high sink rate landing during flight testing by McDonnell Douglas.

[@nopenotme6369]

First flight 2/25. I see why you released I today.

[@peterbradshaw8018]

This is what book keeping aficionados watch for kicks.

[@danmathers141]

I flew one on North Central Airlines.

[@N330AA]

Wow, i've got a lot of respect of Vesna Vulović

[@RoyxlPhxntom]

Anyone else laugh at the clip of the bouncing DC-9/MD-80 @24:51? 😂😅 💪('ω'💪)

[@johnosbourn4312]

The B-29's official name is Superfortress, not Stratobomber.

[@macjim]

Somewhat ironic that they would die in the aircraft they designed… the BAC1-11

[@Sacto1654]

I'm actually surprised aerodynamicists didn't discover the deep stall problem during the development of the Martin XB-51.

[@AndrewG1989]

Was the Douglas DC-9 aircraft as good and efficient. Or was it a aircraft that had lots of problems.

[@johnyoung1128]

I was a mechanic doing maintenance on this type for several years and I found it a reliable and well engineered aircraft. The pilots who worked for the same company as myself liked them too, they liked its handling and performance.
