So I heard of this controversy a while ago as a kid, but I only just reheard it, and it's really bothering me!

The problem is that if you have a propellor airplane on a conveyer belt, can the airplane take off? Suppose that the plane needs to take off as normal and the conveyer is traveling at the take off speed of the plane.

Before I share the answer, or so claimed as such, I want to hear what you guys think and why?

Heres a little diagram to explain better.

I think that the plane would not be able to take off because the plane needs to be moving forwards to create lift.

Tough riddle! As far as I can recall from my physics lectures there isn't a real answer to it or rather there are multiple answers.

If the conveyer belt instantly matches the exact take-off speed of the airplane, then the answer would be no since the airplane would be stationary and therefore could not produce any uplift.

On the other hand, I think I can recall having seen this on Mythbusters once. I won't spoil the outcome tho ;)
