Mythbusters - Anyone see something that will stop 6000 page threads?

ive read the first thread, prob posted in it, and i cant recall if i said it would or it wouldnt.

ive read ~half of this thread, and still dont have a concrete opinion.

physics and math is NOT my thing by ANY MEANS.

but, i have a question… If the plane, in theory according to some of you, will take off, then why do planes need wings to fly? the way im understanding it (and correct me if im wrong) is that a plane needs air moving over the wings to create lift. SO, to the people saying that it will take off, shouldnt a plane be able to fly without wings according to your theory? and if the treadmill is going “backwards” to counteract the plane going forwards, how would the wheels of the plane spin without some kind of opposite force pushing the plane the opposite way as the treadmill is going? wouldnt the treadmill just move the whole plane backwards?

i know i should refer to Fry’s sig before posting, but i honestly dont really understand this so someone feel free to explain it to me and tell me im completely wrong, because i really would like to understand it lol
