Three Engined Aircraft, what happened?

Thanks to Skillshare for sponsoring the video, the first 500 people to use the link will get their first 2 months free: skl.sh/mentour2
Some of the most beautiful aircraft ever made had 3 jet engines. We are talking about the Lockheed L1011 Tristar, the Boeing 727, the MD11 and the DC10, to name a few.
Why are these great aircraft not around in great numbers anymore?
In todays video I will explain the rise and fall of the Tri-Jet.
Why were they needed to start with? What happened that made them obsolete and is there any future for the tri-jets going forward?

[@valuedhumanoid6574]

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.

i wish i could have been on an L-1011 my first flight was a trijet though a northwest death cruiser to MSP in 2005 to see family for christmas

[@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.

[@Bartonovich52]

@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.

Did you know that back in the early '70s Boeing had plans to develop a trijet version of the 747 with a shorter fuselage? A major redesign of the wings would have been necessary and it would have much different handling characteristics, so Boeing instead decided to develop a shorter 747 that still had four engines, resulting in the 747SP.

that trijet version of the 747 (known as the 300 before the real big hump 300 later on) has always been a big what if to me on one hand i think it would have done very well due to timing size and economics but on the other hand due to market crowding and fuel and pax numbers etc at the time i have a feeling it would have tanked

+therealnightwriter Unless you designed the rear fuselage with some extra space to begin with... 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!

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.

Every time you say "Hope you are doing absolutely fantastic" you bring a smile to my face. Thank You :)

@0:17 I flew with a three engined Tupolev to Bulgaria in 2004.

[@Lloyd2605]

Another great video mate.

[@susannedorzbach3529]

I loved the Lockheed Tristar, she was such a Beauty. Flew on several times. Like your videos and miss not a single one. Thumbs up.

[@paulperrottet113]

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

[@megadronGR]

you are very talented and the way you explain aviation stuff is really flawless

[@brendanomara339]

Another super interesting video! Thanks!

[@hitoall123]

Thank you! I wondered why that curious engine in the tail since I saw a trijet for the first time 25 years ago (operated by Swissair for the Asian routes)!

[@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.

[@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.

I really enjoy your talks, very informative and very interesting.

[@vsaprissa]

Excellent technical explanation on aircraft with three engines. Congratulations.

[@Ingenieur1961]

Nowadays ETOPS means: Engines Turning Or Parcels Sinking :-)

[@etiennedanieldodge743]

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.

[@henrygeorge6388]

Thank you my dear Brother for your in-depth analysis of all about Aircraft's GOD bless you immensely Amen.....

[@AhmedKhaled-sw3bl]

Thank you captain love it as usual

[@LtKernelPanic]

I think I prefer the unofficial definition of ETOPS - Engines Turn Or Passengers Swim because it's pretty much true.

[@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.

[@jordyn444]

@@petrosspetrosgali all A310's have been retired, there's still plenty of A300's in service

[@TheOCMarc]

Very informative and interesting. Thanks for making this video.

[@waveymaq4231]

Thanks for telling me more about it Sir.. You explained it well. 👍

[@AlessandroFerrero]

Thank you Captain. Nice video, as always. Don't you think that the tail engine in DC-10 and MD-11 was somehow a weak point and could decrease the overall reliability? In case a failure occurred to the engine, involving an explosion, this might have damaged the fin and the vertical rudder. If I remember it correctly, there were similar accidents caused by this. I flew several times on a DC-10 and an MD-11, and I've to confess that I didn't feel as comfortable as when I flew a 747, especially on the DC-10. And I never liked that little "shudder" when it took off...

[@antoinebonnet4340]

actually I think the main weakness was that all 3 hydraulic systems were close to the tail engine. In one accident (United 232) it exploded and caused a total hydraulic loss.

[@ltr4300]

It did happen once or twice, but I'd say the trade-off to that point was you also got a more robust structure in the rear of the aircraft, and after the accident Antoine described they did a lot of improvement to the hydraulics, previously the systems were not well isolated in ways that a catastrophic leak in portion of the system would not cause the entire circuit to deplete and become unusable...that alone would have preserved some control ability for U232 after that uncontained disc failure. Any time an engine shells out it's gonna be a bad day, doesn't matter where it's mounted. Throwing blades is one thing, but when a disc scatters stuff is going to get torn up. And a high probability something's coming through the cabin if it's a wing mount engine. So personally I'd say there really is no good or bad place for that type of failure. People are generally left with a bad impression of trijets because there were so many horrific accidents involving them...but upon scrutiny it seems that most had nothing to do with the actual design per se, many were due to improper repair or inspections, or mishandling by ground support personnel. A lot of the problems thus seemed to be that they were somewhat revolutionary and got ahead of the curve for the people who were tasked with keeping them flying.

[@Siggy4844]

Yep, Sioux City comes to mind. Tail engine blew it's fan disk and took out all three hydraulic lines. When I was younger our family often went on vacation by plane but my mom refused to go on a DC10, it's all we could do to get her on a plane at all. I loved flying but always felt uneasy going on DC9s, especially boarding at the rear when handrails were wet from condensation and the backs of the engines were covered in soot. My best flying experiences have been on Tupolevs and 747s.

[@soumikchatterjee956]

Once again an amazing video. Cheers! Although I had a question that why aren't flight attendants given basic flying training in case of incapacitation of both pilots in the cockpit. I'll be glad if u could answer this. Thanks :)

[@MentourPilot]

Because the risk is so remote.

[@soumikchatterjee956]

Mentour Pilot Thank you sir. :)

[@r.wehner8802]

Also they wouldn't be able to enter the cockpit, right? Without going into safety related topics.

[@jamesneilsongrahamloveinth1301]

Some kind of parachute system for passengers would make me feel safer . . .

[@Linescrew1Canada]

James Neilson Graham Opening up a door with a pressurized cabin is next to impossible.

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.

[@nathanialsolomon5864]

Excellent report you are giving us about aircraft sir thank you very much

ETOPS = Engines Turn Or Passengers Swim

Hahaha ... now that's an acronym difficult to forget.

ETOPS:Extended range twin engine operation Standard

[@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!!

[@chrisyan695]

There’s one Wendover Production viewer

[@b.maguire3506]

Thanks for This! Cheers!
