most of u r smart, but not street smart. get ur face out of the books and look at reality. actually, even in theory, it still wouldnt fly. this thing isnt a freaken fighter jet which creates thrust out of no where! i mean, even those need a runway (small but they still count). it needs its momentum and speed over a distance. as i said before which no one read i guess, do u EVER see a plane launching into the air from a dead stop? NO they travel, and pick up speed/lift THEN proceed to the flying.
Did you read any of the explanations? The planes don't just pick themselves off the ground, it accelerates even though the conveyor belt moves. And fighter jets use these things called JET ENGINES to magically create thrust. And fortunately for us, the US military was kind enough to let us use them on commercial and private planes to also magically create thrust.
And what does this have to do with street smarts? It's an imaginary situation that will never happen in real life. This is, by definition, a book problem.
