A few things:

What I bolded breaks the problem's statement - The treadmill moves at the same SPEED as the plane. If the plane is motionless, the treadmill is as well.

Running on a treadmill and having a plane on a treadmill are two TOTALLY different things. You cannot compare the two. However, if you have rollerskates on the treadmill...
