I hope this doesn't get to almost 500 pages like this forum on the same subject: http://forum.physorg.com/index.php?s=314...05&#entry157036

How can I not hang around on the wheels, the plane before it gains any lift from the air has to make it to 150mph or whatever speed we feel is acceptable for lift off. Which means the wheels have to get the plane to that air speed before we have lift off. If the conveyor is reversing as fast as the plane is thrusting forward, I'm still 51% convinced that it ain't going anywhere! lol.
