"MYTHBUSTERS" CONTINUES TO MAKE SCIENCE COOL WITH SEVEN ALL-NEW EPISODES BEGINNING OCTOBER 31...

...Airplane Hour
(Weds., December 12 at 9 PM ET/PT)
Adam and Jamie find out if either of them can safely land a Boeing 747-400 on a runway in varying weather conditions. Meanwhile, Kari, Tory and Grant risk life and limb to investigate skydiving myths regularly featured in Hollywood action films. Is it possible to catch up with someone in freefall if that person jumps out a plane before you do? Can you really hold a conversation during freefall? And would you survive if you opened your parachute only a few feet off the ground? Finally, Adam and Jamie carefully navigate their way through a myth that has baffled everyone from web bloggers to pilots. If a plane is traveling at takeoff speed on a conveyor belt, and the belt is matching that speed in the opposite direction, can the plane take off? Extensive small-scale testing with a super treadmill and a nearly uncontrollable model airplane don't completely resolve the myth, so our flight cadets supersize the myth with help from a willing pilot and his Ultralight flying machine.

so what do you guys think about this? :D

its really dependant on the situation... I mean if the treadmill's job is to keep the plane steady, no way in hell will it take off (if the treadmill keeps upwith plane's forward motion) but if the treadmill is set at a certain speed (lets say 10 miles), the plane just needs to make up that ground speed (so on a 0 wind condition a 152 will go about 65 gs to TO at 55) but will it make it take off in a short distance? I highly doubt it lol
 
Isn't this whole treadmill thing the same as a seaplane taking off upstream in a river?

I love doing splash landings in one of these!

All that happens is that the wheels rotate at twice their normal takeoff speed.

You could get into issues with bearings overheating, and an excess of rotational kinetic energy. But remember an airplane produces thrust with respect to the air and the wing produces lift with respect to the airflow.

The whole thing was to fool people that think airplanes work like cars where the engine drives the wheels.

btw I LOVE mythbusters:D

:yeahthat:

I would suggest anyone who is not positive that the plane will have NO trouble getting airborne, WATCH, Video Tape, TIVO, DVR, whatever, make sure you watch that Mythbusters episode before questioning it on this forum.
