Humans don't weigh as much as cargo. The biggest two engine cargo transport out there is... The Kawasaki C-2? It can carry 37 tonnes. The 777F can carry 103 tonnes, which is still 50 behind the 747 and An-124, and it's much more delicate.

I will always have a soft spot for quad jets. They spawned the genesis of the jet age and long haul nonstop travel. The Comet, 707, and DC-8, and later Concorde, showed us what was possible and what the future of air travel would look like. Even though quad jets are quickly being retired or being used solely for freight, they represent the biggest changes in civil aviation.
An analogy: 2WD vehicles versus AWD/4WD vehicles. 2WD is fine for the bulk of driving and efficient for not dragging all that extra weight and reciprocating mass around. But AWD/4WD can get you out of a bind when conditions get rough/slippery.

One engine planes do have serious issues including maintenance and safety. Engines mounted inside of the tail are harder to maintenance than the ones below the wings. Also a single engine failure would be deadly. If a Cessna has it’s only propeller fail the pilot can usually land on a road or felid as their plane is very light.
Travels of Munch If 1 of the 2 engines fails the plane still has an engine and can make a controlled decent into an airport. If an engine even has a failure on a single engine plane their is no thrust.
someday or the other we will need them back . the situation in the world will not remain the same forever and so will the population. surely the quad-jets will rise again .long live 747 ,long live quadjets
13:48 This frame proves that the pictures are not to scale. I think that the age of the quad jet may simply be on hiatus until demand for air travel increases again. However, by the time the quads come back, it will be hard to say what the planes will run on. As for the A380, I'm surprised JAL and All Nippon didn't take them on. In 1990's Japan, air travel was so popular that they used 747s as commuter jets.
@MichaelBujaki I recall reading that JAL saw the operating efficiency to be very poor for the A380 for a commuter style flights because it takes more crew and time to load and unload 550+ passengers via A380 vs the Boeing 777
I think we will see a quad jet super bulk freighter. 4 GE-9X are suitable for 840 T MTOW (200 T larger than the AN-225, but looking similar). The aircraft weights would compose: 320 T OEW; 320 T PL; 320 T Fuel, with the latter two being limited to a total of 520 T. The cargo bay would be 7 metres high and 6-sided in cross-section to allow for wheels (24 x 35 tonne capacity - 6-axle per side compared to 7-axle for AN-225) and loads as wide as 11 metres. It would have a cargo bay 60 metres long. In essence it could carry 4 F-35 fighters just rolled in. It could carry aircraft hulls as large as the 777X. It could drop some huge water loads on bush fires. It would a heavy stand area between the wheels and special detachable legs for loading really heavy cargo. While there is only one AN-225, a heavy lift aircraft with good military and other applications should sell in the hundreds.
It would also destroy any runway it landed on. The A380 was already limited on the number of runways that could handle it's weight. You aren't going to see it any time soon.
It shouldn't damage runways - it only has the wheel load of anA350-900. 7 axles per side like the AN225 would reduce wheel load to 28 T/wheel. 8 axles per side would give 26.25T/wheel. But the main issue is to have sufficient spacing between each wheel.
The only way I can see quadjets returning is if some new technology like hydrogen power required more engines to match the thrust of conventional turbofans
Boeing : 4 engine(707 and 747) Airbus : 2 engine(a220 a300 a310 a320 a330 a350) Lockheed and md : 3 engine(L-1011 dc10 and md11) Antonov : SIX BUOY(Antonov AN-225)
The thing with the Concorde and the Comet was that they were designed and built in an era when aircraft materials and technology were in their infancy. Both aircraft were way ahead of their time........ in particular, the Comet. Concorde had the first "sort of fly by wire" system and many other very clever advances and with the Comet........ the shape of the windows and the materials used for her construction. Had both of them had a bit more modern materials, had a bit more luck and not fallen foul of the underhand tactics of Boeing, things would be a lot different now.🇬🇧🇬🇧✌✌
Quads are likely to be relegated to freighter only in the foreseeable future. You don't need that level of lifting capability for 250-350 people anymore. Some people joke that single engine airliners are the next new thing but they would have no built-in redundancy.

I think that the quad jets are going to be gone especially because of COVID. It is really sad since I will never get to fly on one when I have dreamed of stepping foot on an A380 of 747.
Splendid video. Will we ever see another western build rear-engine mounted T-tail design? I’m afraid the answer is the same as the quad, but could make for a very interesting video.
I've heard one of a design of a DC-10 have a fatal flaw. Not to mention its third engine on its tail! If that goes out or at least blows up, then the whole plane can go bye bye with people in it! That's as far as I've heard. I can see why airlines like Air New Zealand switched to a quad jet Boeing 747s after DC-10. Furthermore Airbus went with a smaller quad jet design the A340 instead of DC-10 or Lockheed L-1011. Probably because of the fear of a fatal flaw design on tri jets? Personally I'm fine with new ETOPS twin jets but I prefer an A380 because of size and sheer comfort of the widest fuselage mean having the widest economy class seats. I guess I have to wait for upcoming B777x. Haven't flown A350s but A330/340 seats were cramped! A 9 abreast config 777 is good though. I haven't had fear of flying in twin jet when I was young esp with B767s.
The quad jets are over. Look to the business and private jets. The new Gulfstream G800 have a range of 14000km, that will say from Amsterdam to Los Angeles. I think that Airbus with his develop partners gonna work on fuel and noise reduction. And a greater range.
Are smaller engines unable to have the SFC that bigger engines do? Otherwise I don't see how engine number is an issue. If you have A320NEOs in your fleet, having a long haul quad jet that also uses the same PW1100Gs would save a lot on maintenances too.
Bring back tri-jets 😢❤ (MD 10-11 like) 🥺 Boeing I know you can, please Airbus A380 will be missed too 🤧 a legend like the Boeing 747 and the Concorde 🥲 Thank you McDonnell Douglas, Boeing, Airbus, Aérospatiale and BAC for those legends
The population of the planet keeps growing. Eventually the demand for travel will also continue to grow. I am sure there will be room for 4-engine aircraft, especially if they figure out a way to make it more economic and environmentally-friendly.
a single GE9X engine is strong as all 4 A340 engines,it means B 777 is stronger far from A340.I think 4 engines for long range,not for higher survive percent
I sincerely doubt that quads will be used outside of freighter & military uses 😦! When AB ditched the freighter varient of the 380, they sent to the gillatine million's of man/hour's & truck loads of money 💰!
life is like a circle...so there wil be ups and downs...it will surely regain the momentum... i feel quad jets will again be launched with much more popularity :D
Aren’t we forgetting the Convair 880? And 727 whisperliner? I can hardly yell that loud, never mind a whisper. And Concorde being phased out for more efficient higher capacity aircraft. Not ten minutes later, more efficient higher capacity aircraft being phased out for smaller aircraft. They’d be flying CRJ’s transatlantic if the could find a way. And why not fly over Antarctica? McMurdo-Williams Field is surely large enough, and density altitude couldn’t possibly be an issue.
I like quadjets more, my favourite plane is a quadjet, the Airbus A340. I'm sure quadjets may appear in the future for low-emissions aeroplanes, because if the required power cannot be achieved by two engines, three or four may become more popular again. For example, a long-haul hydrogen aeroplane may need three or four engines if they can't get enough from two. While two engines can be very efficient, there'll come a point when twinjets reach their limit, and quadjets may come back. Aviation is possibly over-reliant on ETOPS. ETOPS could fail one day and quadjets will make a comeback.✈️
On the Atlantic run, I don't think the 380/747 really work. There are too many airlines flying that route. But, the distances to Asia from the United States warrant the use of quadjets like the above mentioned aircraft. But, the idea of using single aisle aircraft on the Atlantic run is absurd. Boeing should retool the 767 to be a smaller, more efficient aircraft to complete with the 321.
You guys speak too soon, the IL-96 400 will be a four engine jet... And having flown in the A340 a few times, it is insuring a trouble free flight with four engines peace of mind over the Atlantic... They can be also efficient for the right reasons other than economic ones... One of them been trouble free 30,000 hours of flight time on "on wing" power been used al half power VS 15,000 hours or less of twin engine power at 100% and instead of adding more fuel efficiency savings you are adding more maintenance to more expensive engines and down time of the aircraft....
@@alexandernorman5337 Vibration and metal fatigue take their toll on the engines, they are not without their problems!... Specially the big Trent engines, that perhaps those were the Achilles hill of the Airbus A380, ask Singapore Airlines!...
@@paveldeveraux2729 - Yeah. I'm just saying that regardless of the decision to use four engines or two engines, they are usually only used at less than 30% in cruise.

I think that the quad jets are going to be gone especially because of COVID. It is really sad since I will never get to fly on one when I have dreamed of stepping foot on an A380 of 747.
Splendid video. Will we ever see another western build rear-engine mounted T-tail design? I’m afraid the answer is the same as the quad, but could make for a very interesting video.
The A380 will make it's comeback, world middleclass and overall population keeps rising, eventually we need these giants back.
I really love your content ❤️
I've heard one of a design of a DC-10 have a fatal flaw. Not to mention its third engine on its tail! If that goes out or at least blows up, then the whole plane can go bye bye with people in it! That's as far as I've heard. I can see why airlines like Air New Zealand switched to a quad jet Boeing 747s after DC-10. Furthermore Airbus went with a smaller quad jet design the A340 instead of DC-10 or Lockheed L-1011. Probably because of the fear of a fatal flaw design on tri jets?
Personally I'm fine with new ETOPS twin jets but I prefer an A380 because of size and sheer comfort of the widest fuselage mean having the widest economy class seats. I guess I have to wait for upcoming B777x. Haven't flown A350s but A330/340 seats were cramped! A 9 abreast config 777 is good though. I haven't had fear of flying in twin jet when I was young esp with B767s.
I believe that it is fair to say the age of quadjets is a bygone era, that’s what…
Time for supersonic era now 🤤☝🏻️
New "Son of Concorde" is coming in 2029 ❤
Great video but I wish the MD-11 was not ommitted in the history lesson.
I think quad jets are more beautiful than twin jets😍
Simple Flying guy: I am a Professor of ETOPS!
The quad jets are over. Look to the business and private jets. The new Gulfstream G800 have a range of 14000km, that will say from Amsterdam to Los Angeles. I think that Airbus with his develop partners gonna work on fuel and noise reduction. And a greater range.
I think only cargo planes will have 4 engines
Are smaller engines unable to have the SFC that bigger engines do? Otherwise I don't see how engine number is an issue. If you have A320NEOs in your fleet, having a long haul quad jet that also uses the same PW1100Gs would save a lot on maintenances too.
Bring back tri-jets 😢❤ (MD 10-11 like) 🥺 Boeing I know you can, please
Airbus A380 will be missed too 🤧 a legend like the Boeing 747 and the Concorde 🥲
Thank you McDonnell Douglas, Boeing, Airbus, Aérospatiale and BAC for those legends
The A340-600 will always stay my ultimative superstar. Those trendy twin jets are not iconic...
That's because of the below deck toilets where no-one sees you having a quickie !
@@christoohunders5316 haha no😀
I see me trying and failing to explain to my kids how massive 747/A380's were, its something you just have to experiance.
Like the Concord they are amazing to watch take off & land.
Concorde sweety, Concorde.
@@christoohunders5316 spell check changed it & I didn't notice, thanks though.
But quiet pressurized cabins have already been available on (turbo)props?
indeed, but not the above the clouds altitude that you can reach with jets ;)
oh man, I booked a Virgin Atlantic 747-400 flight back in 2019 to fly in 2020. But... We all know what happened...
Hopefully, you will get on a 747-8, that would be awesome.
This era is over. Luckily, modern twinjets like the 787 and A350 are aesthetically much more appealing.
The A350 and 787 are not as beautiful as the 747 and 380.
B-52 Stratofortress: “I’m not like other girls.”
777 - I've got a big pair, these are real.
a380 - oh yeah, I've got 4 of them.
Its over. We will soon see twin hypersonic electric jet engines, powering airplanes cheaply at higher altitudes with less moving parts.
The population of the planet keeps growing. Eventually the demand for travel will also continue to grow. I am sure there will be room for 4-engine aircraft, especially if they figure out a way to make it more economic and environmentally-friendly.
quad jets are over imo so sad
I thought over 1000 dc8s were built just 556
And there were MANY variants !!
@@christoohunders5316 exactly
Noice
Yass i got a heart
Quadjets are done. The future of aviation will be Supersonic and/or electric.
no ETOPS restrictions
a single GE9X engine is strong as all 4 A340 engines,it means B 777 is stronger far from A340.I think 4 engines for long range,not for higher survive percent
I sincerely doubt that quads will be used outside of freighter & military uses 😦! When AB ditched the freighter varient of the 380, they sent to the gillatine million's of man/hour's & truck loads of money 💰!
life is like a circle...so there wil be ups and downs...it will surely regain the momentum...
i feel quad jets will again be launched with much more popularity :D
I hope 747-8 will kick start along with A380-f
Aren’t we forgetting the Convair 880?
And 727 whisperliner? I can hardly yell that loud, never mind a whisper.
And Concorde being phased out for more efficient higher capacity aircraft. Not ten minutes later, more efficient higher capacity aircraft being phased out for smaller aircraft. They’d be flying CRJ’s transatlantic if the could find a way.
And why not fly over Antarctica? McMurdo-Williams Field is surely large enough, and density altitude couldn’t possibly be an issue.
ETOPS.... Engines Turn Or Passengers Swim.
I like quadjets more, my favourite plane is a quadjet, the Airbus A340. I'm sure quadjets may appear in the future for low-emissions aeroplanes, because if the required power cannot be achieved by two engines, three or four may become more popular again. For example, a long-haul hydrogen aeroplane may need three or four engines if they can't get enough from two. While two engines can be very efficient, there'll come a point when twinjets reach their limit, and quadjets may come back. Aviation is possibly over-reliant on ETOPS. ETOPS could fail one day and quadjets will make a comeback.✈️
I think twin jets over oceans is not a good idea.
On the Atlantic run, I don't think the 380/747 really work. There are too many airlines flying that route.
But, the distances to Asia from the United States warrant the use of quadjets like the above mentioned aircraft.
But, the idea of using single aisle aircraft on the Atlantic run is absurd.
Boeing should retool the 767 to be a smaller, more efficient aircraft to complete with the 321.
747-8f. F indeed.
four 4 me!
Am I the only one who thinks the front of the a380 looks ugly and overstretched
Sadly I believe the quad jet era is over. It had its glory days.
You guys speak too soon, the IL-96 400 will be a four engine jet... And having flown in the A340 a few times, it is insuring a trouble free flight with four engines peace of mind over the Atlantic... They can be also efficient for the right reasons other than economic ones... One of them been trouble free 30,000 hours of flight time on "on wing" power been used al half power VS 15,000 hours or less of twin engine power at 100% and instead of adding more fuel efficiency savings you are adding more maintenance to more expensive engines and down time of the aircraft....
Modern jet engines are only used at full power for a few minutes at takeoff. Whether a quadjet or a twinjet, the engines only run at 20-25% in cruise.
@@alexandernorman5337 Vibration and metal fatigue take their toll on the engines, they are not without their problems!... Specially the big Trent engines, that perhaps those were the Achilles hill of the Airbus A380, ask Singapore Airlines!...
@@paveldeveraux2729 - Yeah. I'm just saying that regardless of the decision to use four engines or two engines, they are usually only used at less than 30% in cruise. You don't have to work the engines harder to accommodate a two engine aircraft. The airplane manufacturer sizes their selected engine appropriately.
@@alexandernorman5337 Its because of the thin air at altitude, the trust of an engine is only 25% at 30,000 ft but still needs to overcame aircraft drag.. Thrust available = Q(V1 - V2... Power required for cruise speed is 66%..
HOPEFULLY Boeing will make a new 747 version at least for freight in 20-30 years.
