My first jet flight was in an L1011. I sat down in my seat and looked at my dad and with a worried look and asked him if this thing was really going to fly! It was bigger that our house! He chuckled and smiled and told me not to worry as long as the plane was less than half full (yes, his sense of humor was a bit hard growing up with) and as I sat there watching the plane fill up to max capacity, I looked out the window to see a massive train of luggage pull up and start filling up the belly. I was freaking out. I will never forget that feeling when we were accelerating down the runway, my little ass pushed back into the seat thinking this is it....we're not getting airborne....then we did and the rest of the flight was spent in wonder looking out at 30,000 feet.

[@marcusdamberger]

I got to fly a Tri-Star L1011 back in 96' to Germany that summer. It had a very smooth flight, flown by Rich International Airways. However, you could tell by this point the passenger interior was getting rather tired. No seat back LCD screens to speak of, with a pull down projection screen for each section. A leftover from the original 70's film projection setup, but now with a LCD projector. So everyone had to close their blinds for anyone to see the screen. Some seats earphone plugs didn't work.. You could tell maintenance was beginning to slip. When I moved to Roswell, NM for a job in the early 2000's, I discovered that the old Rich International Airways L-1011's were now all stored at Roswell International Air Center for eventual parts and scrap disposal. I was a little sad to see that, as I really enjoyed my time aboard those L-1011's that summer. Even had an "indecent" coming into Chicago where the pilot had to abort the landing on final. When they did we flew all the way across O'Hare and finally landed 20mins later. So I got an extra 20mins of time aboard the L-1011 on my last flight. Interestingly, RI would fly through Gander Newfoundland to and from Europe. So that always added an interesting aspect to the flight. I really liked the look of the L-1011 over the DC-10 or MD-11. Alas, most of those 1011's are no longer flying, a few DC-10's with random operators and lots of MD-11's with FedEx these days. Such as the DC-10s 10 Tanker Air Carrier uses for firefighting.

[@ltr4300]

I remember my first and only L-1011 flight well because I was about 9, very into aircraft (still am) and was a regular flier at that age because I went back and forth between Denver and St Louis due to divorced parents. Normally this was on a 737 with Frontier Airlines, but we were up in Montana when it came time for me to go to STL, so that necessitated some backtracking and switching to another carrier (maybe Delta? Can't remember) out of Salt Lake City I think. That's where I boarded the 1011. I was very impressed...I'd been on a 747 before so it didn't completely blow my mind but it was impressive. But the reason I remember it so well is that it was rainy and blustery in STL and the big bird came down once kinda tentatively, then got ballooned by a headwind gust (felt like) before the spoilers came out, floated quite a ways before coming down hard and the crew put the nose down and threw 'er into reverse harder than I've ever felt before...seriously, it made me wonder if my belt was gonna keep me in the seat...LOL...and the runway was wet, which didn't help. I knew the layout of Lambert Int'l like the back of my hand, and as I watched landmark parts of the terminal and peripheral installations rushing past alarmingly fast I actually began to wonder if this thing was gonna stop or not. When I began to see long term parking I decided nope, we're humped. But we managed to hook a turn onto the last taxiway, tail-high and anti-skid chattering I assume, you could feel the rhythmic pulsing of traction so that or we were on the cusp on a sideways skid....it was quite invigorating! One of those where the whole cabin goes completely silent and then you hear a couple hundred folks all start to breathe and slowly talk again in very relieved tones...I think that was probably the closest I've ever had to being in any "incident" on an airliner. Actually feeling strong cornering forces on the ground was disturbing. But Captain Chaos drifted it like a boss, apparently.

@Dan Jackson, no it wasn’t. It just wasn’t as lucky as the L-1011. The L-1011 had a triple engine failure but luckily didn’t crash. The DC-10 had no such incident. Shrapnel impacted every one of the L-1011s four hydraulic systems after a centre engine fan explosion. Only luck kept one system intact. The L-1011s stabilizer jammed in the full nose up position. Never happened to a DC-10. Only luck kept it from crashing. The L-1011 was late into service, not very many were made, it was a maintenance nightmare, production ended early, and they were retired early. It only flew a fraction of the hours the DC-10 did. The TU-114 was “safer” than the L-1011 for the same reasons. The L-1011 couldn’t even be certified in its original form due to engines that would explode on impact with birds.

For over 40 years I have flown extensively, and many flights were on DC10s, L1011s. Between the two, I found the DC10 to be the quieter of the two. I also thought it looked better. Specifically, American. Delta, TWA and Eastern flew L1011s. I mainly traveled on Delta, but occasionally, TWA and Eastern. I was a Road Warrior for 17 years. From the late 80s up until mid 2000s. Love everything about commercial aviation, and thankful for KZbin!

[@catjudo1]

My grandfather flew for Delta for 27 years and during his time, they rented some DC-10s before taking delivery on their L-1011s. When I asked him which he enjoyed flying more, he said that the DC-10 was a better handling airplane and responded quicker to pilot input, but that the L-1011 was so much more advanced and so much more refined that he was glad his later career saw him in the Lockheed. His all-time favorite airliner to fly, however, was the Convair 880. He really liked that plane.

I was working for Rolls-Royce in the late 60s when the first RB211 3 shaft gas turbines were being designed and developed. The first aircraft they were intended to be used on were the Lockheed L1011 so tri-jets were certainly being more than thought about before the 1970s as mentioned here. I left RR just before the 'crash' in 1970 caused by the design problems with carbon fibre fan blades and the extra cost in using titanium (which is now standard). I rejoined RR a few years later and remained until retirement but, as I recall, one of the problem with centre engine was that S shaped intake duct which meant air intake was inevitably restricted. My field was the design of electronic measurement and control systems on test beds and rigs so the details of aerodynamic design were almost as much a mystery to me as to the general public :) Like all your videos, very well presented and explained.

ETOPS has my favourite backronym ever - Engines Turn or Passengers Swim

[@msmeyersmd8]

I loved the 727. Gorgeous airplane. Everybody moved too close to airports and then started complaining. So no more 727 hot rods. The best airline flight also included the best airline meal I ever had. If you are young, they really used to serve full meals with metal silverware and everything. But, I digress. It was an L-1011 TriStar. Smooth and quiet. Plus it looked sexy. Great curves...including the S-duct. Mmmmm. I always hated the looks of the DC-10. The third engine always looked like an afterthought to me. Like they were too lazy to do it right so they just slapped it up top in the vertical stabilizer. My second best passenger flight experience was in a C-5 Galaxy. Smooth and quiet except for hearing the flap and gear motors. But I liked that. Ironically, that was the second best meal I’ve ever been served on an airplane. We were heading off to the Gulf War. I appreciated the meal tremendously. The only draw back to the C-5? There’s no “people eaters” or gates at Dover. To get to the rearward facing passenger compartment a climb up a steep ~14 foot ladder is required. Not easy, or stabile with 60+ pounds on your back. To this day and hundreds of airline flights later. It’s the only airplane where I could not feel when we actually landed. I heard the power reduction for descent. Heard the flap motor and gear doors open and the gear clunk into down and locked position...and then we were taxiing. Amazing. Still amazing to think about that today. Another memory from that time long ago was arriving at Dover and as far as he eye could see were parked C-5s being loaded or unloaded or fueled. And these were all on the ground in Dover. Imagine how many were inbound or outbound from Europe and the ME. And on the ground overseas. I was an airplane buff but my jaw dropped when I saw how many C-5s were on the ground in Dover. Still in awe at the military power projection that represented.

[@jayreiter268]

The L1011 had its problems that we worked regularly. But it was the best engineered aircraft I worked on. Take for instance the elevator. The elevator was not a flight control in the general sense. The elevator was a "Flap" for the Stabilator that increased the camber of the stabilator at low speed. This allowed less drag and higher cruse speeds. The manuals used the ATA chapter format that was consistent from Maintenance Manual to Illustrated parts Manual to Wiring Manual. Much better than Boeing. The triwing screws were an ATA spec. for this series aircraft the DC10 had them also. To compound the problem the L10 used Titainum screws. I did not understand this either eight tool bits to take the place of three Phillips bits. We had experience with Douglas's Reed & Prince screws on the pistons. I am partial as I was with the L10 from introduction to Mojave.--Jay

Maybe, if there's ever gonna be any demand for a really huge aircraft with a capacity of 400-500 passengers again, i.e. something like the 747 or the A380, that's where Tri-Jets might come back again in the future.

I do agree that a modern high bypass-ratio turbofan engine would be very difficult to to retro-fit due to their size, but with fuel-efficiency a priority these days, I could see three engines used for take-off & climb to altitude (and remember, there are many airports that require pretty steep climb angles to minimize noise or clear terrain), and then shutting down the third engine (if you had retractable intake ducts to eliminate drag) for a very fuel-efficient cruise on the two main engines- it would also increase the T.B.O. of the third engine, saving on maintenance costs. Any aircraft manufacturers/designers who read this, please feel free to send me obscene amounts of money and use my idea!

[@fidelcatsro6948]

ETOPS should sound like ERTEOS doesnt it?? well i think the whoever who came up with ''ETOPS'' was really thinking Engine Turns Or Passengers Swim!!

I loved flying in the DC10. I flew in them when Sir Freddie Laker had the Skytrain service. When the engine fell off the wing of that DC10 in Chicago - a month before my flight to California, the aircraft was changed to a 707 and later a Tristar.

[@Maxfli82]

Love the setting of this video! You just need your couch now in the middle of the runway.

[@tjrtt]

I absolutely loved the tri-star L1011. The dream aircraft of my childhood.

[@PetiteKeyboardist]

ETOPS = Engines Turning or Passengers Screaming. My husband is an airline mechanic...I know what it means.

[@תומרקחלון]

its actually engines turn or passengers swim (as far as i know)

[@oceaninfini3880]

DC-10, one of the most scary plane ever built !

[@trumpsb757sucks5]

The starting 10 years of the aircraft release made a bad reputation on the aircraft till today as you say

I remember travelling in one in the 80 s from Sydney to Europe. Very noisy as my seat was at the back right under the tail engine.

[@TheBoostedDoge]

And one of the most beautiful at the same time

[@ed743-m4t]

I love the fact that Dassault kept the tri-jet formation for their Falcon 7X & 8X and the fact that Boom has decided to make a BEAUTIFUL tri-jet SST.

[@dhananjayabandara9087]

Your videos are very clear. Pronunciation also easily understand. Thanks for your effort captain.

[@laure5333]

Good stuff, mate ! Keep going ! However, on your array of tri-jets examples you forgot to mention the Boeing 727...!!! By far, the fastest of all commercial tri-jets is the Tupolev Tu-154.

[@ryanhunley]

“Boom”? Is that the best name for an airliner?

[@elizabethromeo3432]

my dad flew the DC10, i absolutely love them ! P.S. your content is a gold mine. just like how the courses in the app are wonderful and so helpful. i'm currently doing my type rating on the 777 and feel like i'm in heaven !! Keep on going the great work Mentour !!!

[@TheFrenchPug]

I love all the info you come up with that one would never bother to think about or at least ask about out loud.

[@lorrewatkins5925]

Yea I totally agree, I Love trijets both narrows and wids, L-1011s, DC-10/MD11s Boing 727s, Love Love Love !!

I flew on one of Freddie's L10-11 from Prestwick to Miami in 1981 as a kid loved it.

[@jetsetter8541]

Tristar was the most comfortable lovely aircraft after Concord

[@giomac]

One.more reason: hull becomes noisy, i've flown Tu-154 in 90's and damn it was impossible to sleep, especially with econom class.

[@KapiteinKrentebol]

Blame that on lack of soundproofing, soviet era aircraft are notorious for the amount of noise they produce.

[@paulperrottet113]

Great video. However you did not mention the most popular of all tri-jets, the Boeing-727.

[@jimlawson7789]

One of the pitfalls of placing an engine in the middle of the aerodynamic controls is that an engine failure may result in total loss of control.

[@randysmith4433]

As always very informative and impressive knowledge of aircraft. Flown on many tristar jets loved the sound and the ride.

[@andrewcruz1931]

Lol mentour ! That ending was classic ! Did you reach V1?

[@trekkermueth3074]

L-1011 was smooth and quiet. One of my favorite aircraft. I still would prefer to have more than 2 engines when crossing the ocean. I think there's value in extra redundancy and I'll pay extra for it!

[@Bartonovich52]

An L-1011 once lost all three engines.

[@wizardmix]

I do miss those L1011s.

[@dpm-jt8rj]

Those RB211s were sweet. I always loved sitting to the back of them during a flight because the hum of those engines put me right to sleep!

[@moi01887]

Rolls-Royce: aero engines of the gods.

[@austindarrenor]

The L1011 had to be the most beautiful airplane ever built. Runners up: The 707 and the Super Connie.

[@wizardmix]

Gary Gray I also think the 757 is a beautiful plane. Same dolphin nose

[@bobbydean6483]

Love the L-1011 most advanced aircraft of it's time, lockeeds last commercial airliner. Ruined by Jimmy Carter.

[@anandkumarmusic]

You know, your videos are amazing.. never knew so so so much about aviation before your channel!! Thanks.

[@gerardmoran9560]

Great video as usual but I'm mortally wounded that you failed to mention the love of my life for 7 years- B-727!

[@muddshshshark]

Ive only flown a few times , but I did get to fly on the L1011 and DC10 Netherlands I think

[@jordyn444]

working at fedex express we load dc-10 and md-11 every night but they're being phased out for the 777

[@petrosspetrosgali]

Are the A300s and 310s still flying? They’ve been talking about phasing those out for like 10 years.

As kid, watching that 3rd engine standing above, and with the loud sound from the old turbojets... Gotta admit I was scared about them 😂🤣 Now, the design and sound, is so nostalgic 😢

[@carouselred8994]

Great video. Love this stuff. As he mentioned, still see them -mostly DC 10s - as freighters.

[@nighthawkvc25a]

Engines Turn Or Passengers Swim :) There's a more in-depth explanation into ETOPS at the Wendover Productions channel, which mentions that ETOPS is not just about the aircraft landing safely to the nearest airport but also consists of airlines having a plan to accommodate the passengers at the unexpected location.

Extended range twin operations performance standards I think

[@donaldstanfield8862]

When landing, how do you assure the nose wheel is steered straight ahead?

[@KingdaToro]

You use the rudder pedals to stay on the centerline during the takeoff and landing rolls. They control both the rudder and nosewheel when the plane is on the ground. When taxiing, you use the nosewheel tiller instead, which allows much sharper turns than the rudder pedals. There's a system that centers the nosewheel whenever there's no weight on it.

[@avamendez1272]

Donald Stanfield we use the rudder pedals to control direction during the rollout. once taxi speed is reached, the tiller is used

[@mcplutt]

Above a certain speed the nose wheel is locked straight ahead.

[@WANDERER0070]

Look up Captain Joe vids it explains lot about airplanes systems and flying airliners

[@kg4boj]

You don't use the tiller when it's icy, you'll just skid the nosewheel. Intertia is really a bitch when there isn't much traction to be had :-) you don't really use the rudder pedals at all but insted the "tiptoe" brakes on top of the rudder pedals. Top of pedal is for differential braking, bottom is for rudder, which will do absolutely jack all on the ground.

[@parrotkind88]

This video made me subscribe. I don't really know much about aviation, but I LOVE watching aviation videos. I think now, after years of fascination, I will learn a lot from your channel. Love the L-1011 take off. Thank you.
