how do a 50ft oval airplane with long wing fit in a 16ft round concrete wall hole, with no wreckage outside?

Answer 1

Slam it into the wall at 500 mph and with tons of jet fuel, that's how.

Please don't propagate this garbage. The Pentagon was hit by a commercial aircraft, not a missile. There are video and eyewitness accounts.

Commercial jets don't have a lot of structural strength, certainly not compared to concrete. Relative to a concrete wall, they have little mass. There's a reason why they are made of aluminum and light metal alloys instead of steel. can you guess why?

Answer 2

The same way as porcupines copulate.... Very carefully ☺
