Can someone answer this question?

I think that it dependes on the type of plane. A plane with a propellor like a KC-130 that can generate its own airflow under and over the wings to create its own lift might be able to do it. Watch a plane take off and notice what happens to the wings as the wheels leave the ground. They flex as they take the load of the plane. The plane needs lift from air moving under the wings to take off.

A jet that creats so much thrust that it doesn't need lift to take of should be able to do it also.

I really think that kompressornsc hit the nail partially on the head. Its about thrust and lift.

I missed this as my computer was down....just read the question this morning on a different board and reposted it here awhile..haha. I did just find a "professional" answer to it though. Thought I'd share.

Yeah, I read that but I also talked to two friends who are both pilots and they don't think the thrust would be enough to overcome the effects of the conveyor. :nixweiss
 
hahaha...who knows...I'm on the side that says the plane WILL take off, but I'm nothing close to a physicist or a pilot, so...
 
I just posted this in loved's other thread on this subject b/c i didnt see this one



Planes are propelled by their engines. These engines don't supply power to the wheels. The wheels are free rotating. Because of this, if the runway is moving in the opposite direction of travel, the only thing that would happen is that the wheels would spin twice as fast as the plane is moving forward. it would still have a net forward motion because the jet engines are pushing the plane forward, not the wheels. If this was a car, or any other vehicles that use their wheels to propel them forward, the forward motion of the car plus the equal reverse motion of the conveyor belt would equal out to a net movement of zero. But like I said, the wheels on a plane aren't powered, they just sit there and spin. Unless the wheels blow up from spinning to fast, this plane will take off
