The times they are a-changin’.
This post seems to be older than 15 years—a long time on the internet. It might be outdated.
I first heard about this several months ago. BoingBoing just brought it up again:
Imagine a plane is sitting on a massive conveyor belt, as wide and as long as a runway. The conveyer [sic] belt is designed to exactly match the speed of the wheels, moving in the opposite direction. Can the plane take off?
I know the answer, do you? (without cheating)
