The plane took off! To quote Adam: "I've read literally thousands of pages, of vitriolic commentary and arguments about airplanes on a conveyor belt, but nowhere did I find anyone who'd put an airplane on a conveyor belt." The MythBusters did and was one of the most straightforward mythbustings they've done: plane + conveyor belt = flight. To those who still have trouble wrapping your head around the problem: the wheels on a plane don't matter; they spin freely. The conveyor belt can't keep the plane stationary.
