So, why is there still an argument?[/horrible tailposting]

Wtf? The plane was moving forward...so the treadmill wasn't equal to the plane? Well duh, it's not stationary as the original question seemed to suggest, of course it will take off, it will just take the wheels longer to get up to speed.

It was moving backward relative to the ground at the same speed the plane was moving forward relative to the ground.

That was the trick in the trick question- it seems to suggest that the plane will be stationary, but doesn't actually say so.

No. The wheels actually move twice as fast.
