Ege Erdil says the basic concept of flight using wings and thrust is relatively simple, while making it practically viable is much more difficult.

“was a crucial reason why aircraft technology later become like became more popular so it's not like someone came up with the idea of oh like you can just like use something that just has wings and has a lot of thrust and then that might be able to fly like like that basic idea is not that difficult but then well how do you make it like actually a viable thing that's right well that's much more difficult”
