Subject: RE: BS: The Mythbusters airplane takeoff problem
Hmmm. Well, the propellors on the airplane don't make it go "up", they make it go forward. The fact that it is going forward causes air to flow more and more rapidly over the airfoil (the wings). The airfoil generates "lift" when air is passing rapidly over it from front to back, and that lift causes the wings to be pushed upward and the plane to rise up after a bit and take off from the ground...while the propellors continue to provide forward thrust.

Seems to me that the plane wouldn't be able to generate any lift if it was, in effect, standing relatie to the surrounding air. It would certainly generate thrust (forward movement), but not lift.

You normally take off into the wind if you can, because that provides more lift and a shorter takeoff run.

How am I doing so far?
