Question: Will the plane fly? (warning: nerdy)
I'll be done when you all agree with us that it WILL NOT FLY
There are too many variables in this "question" for it to have an answer. It's pretty much all assumption... With a head wind, yes there is the possibility, without one it will remain stationary.

I can utilize a pair of 20 ft stilts. pfft, I'll take a pic next time I am home ;-)

The prop will pull the plane through the atmosphere. The treadmill will do one of two things depending on how you read the various versions of the question:
1. Wheels will not turn because treadmill is countering their movement while the plane moves down the runway.
2. Wheels spin at 2X the planes ground speed because the treadmill is matching the planes ground speed in the opposite direction.
Either way the plane will move and will take off.
The plane is effectivley decoupled from the treadmill movement (whatever it is) and continues to do what planes do.

There have been countless replies stating the plane will not move and therefore will not create lift. People... PLEASE READ THE RESPONSES TO THIS THREAD! The thrust force applied by the plane's engines/props is applied on the stationary air around it, so the plane will move relative to the air around it. How fast the wheels have to turn to keep up with the plane is irrelevent as long as the bearings don't sieze up. The plane WILL move relative to stationary air and stationary ground and will be able to take off no problem. The wheels just have to spin twice as fast as they normally would to keep up with the treadmill going in reverse.
That's it... LAST time I post that response!
