Can a Plane on a Treadmill Take Off?

Are you saying 1) the rope is tight, or are you saying 2) you are giving the
plane a 100' running start?

If you tie a 100 foot rope to the tail of an airplane (or some other
part of the airframe), attach it to a good strong post, and run the
propellor up to whatever rpm is available, is anyone claiming the
airplane can then lift up say a feet off the ground?

(Assuming the tail doesn't tear off)

(and, a conveyor belt under the airplane is optional)

Didn't think of that -- and maybe your response is tongue
in cheek -- but I had in mind "rope is tight".

Depends on the airplane, certain lpanes are built in such a way that
they can actually attain enough lift just from the prop wash alone.

Other than the ones we call helicopters, I've never heard of such a thing.

Care to elaborate?

How many buckets of prop wash would it take?

Yeah Monk that airplane is called a helicopter.

That completely changes the situation. The plane couldn't take off with a
regular runway if you secured it to a fixed post.

The answer is an obvious YES. I don't know how this thread got as big
as it did :^)

Because it is interesting, and evokes thought.
