@KLM_747 And the A380 is a failed design

@asteroidbook345 I think a 3 deck airliner wouldn't use much more runway, take the 777 and A380 for example:
777-200LR- 11,500 feet
A380-800- 12,300 feet
Following this trend, the triple deck airplane would probably need about 13,100 feet of runway. Jfk longest runway- 14,500 feet. However Heathrow only has 12,800 feet so it might need to sacrifice some payload or get more powerful engines. I think that the double deck 787 looks way better too.

Besides, nobody needs a plane that can carry over 1200 people. If I remember, the A380 can already hold 863 in all economy (exit limit?) @captainBoeing

@asteroidbook345 it is out now! you can go and check here @Dazare

@asteroidbook345 it will not be so large! its length is short. and I have also enhanced the braking so a landing can be done on a short runway also. and take less time to liftoff and it is also twin-engine not a lot of fuel is needed. and its foldable wing is awesome so it can park in any type of gate.

Disadvantages:
Stupidly big
No airport can service it
A lot of engines = a lot of fuel = large carbon footprint
Crazy deck area = high amounts of cleaning = large carbon footprint
Will require a massive runway, probably bigger than even LAX or Atlanta to operate safely
A folding wing on something that large would be a huge structural integrity problem
