I have an extremely intelligent friend that simply cannot wrap his head around this problem. He is just having a hard time separating airspeed from ground speed. For some reason he's having a mental block about the air above the belt not moving WITH the belt.

Another thing I thought was very interesting was that the pilot they hired to test the myth believed the plane would sit there "like a brick". This guy is a stunt pilot. Huh?! How could he not intuitively know this?
