I'm probably the only person in the world who both cares and needs Jason's coverage of the Mythbusters plane/conveyor belt experiment. My hotel here in Aktau doesn't get the Discovery channel, so I actually sat around reloading Jason's live coverage of the show, before going to breakfast (I'm 12 hours ahead... you are all way behind). I'm glad to see that some esoteric engineering details didn't get in the way of the physically correct answer to the question, which is that the plane should (and did) take off.
