Plane on a Conveyor Belt
Don't know if anyone has been watching mythbusters lately, but they're going to test the myth of a plane trying to take off on a conveyor belt tomorrow night at 9pm est.

test 1: model airplane on treadmill and it propelled forward
test 2: model airplane on large sheet of some material being pulled opposite direction (make shift conveyor) and airplane took off
test 3: experimental on 2000' strip of burlap or whatever it was being pulled by truck in opposite direction (make shift conveyor) airplane took off.
worth mentioning: quote from experimental pilot with ten years experience when asked what he thought would happen "I think im going to just sit here like a brick"

This subject is being debated on numerous aviation forums right now with widely divergent views.
For me, the idea was pretty simple. If sufficient airflow over the wing wasn't there, then the plane wasn't going to fly. With no movement of the plane and therefore no airflow, how was this thing supposed to lift off?

But the thing is that he didn't 'sit there like a brick'. The aircraft accelerated from its original position down the 'belt' and reached flying speed. All I saw being demonstrated was that the plane had enough thrust to overcome the rearward 'belt' movement and then move forward fast enough to reach flying speed.
i dont think the first two tests work either because its a trust/weight ratio.. that little plane was like a rocket...
but as im writing this and remembering the episode, i'm starting to think im a re re and am just going to shut up now

but see the test is flawed than... the question is whether the plane would fly off if it and the belt were going the SAME speed... obvious the plane had excess thrust or had faster acceleration than the belt did.
