Does that mean that Mythbusters has to test more then one plane vs treadmill scenarios. I only thought there was one that was really relevant to what an airplane does and what a treadmill does.

The fact is that if the plane is not moving RELATIVE TO THE SURROUNDING AIR, it WILL NOT fly period. How fast the wheels are going, the treadmill is going or the engine is running has no effect. The only exception may be a plane like the Osprey which has large enough propellers to generate enough lift over the wings to fly it.
My plane , without the treadmill , will fly in the air after take off with the engine off, yet I can do a runup say 2500 rpm sitting on the runway without taking off. The engine and propellers have no effect with the brakes on because it is not going forward relative to the air and they wont generate enough lift to do anything but possibly lift the tail...and that would be due to elevator deflection from prop wash.......not generated lift.

Hey wait I've got a new one for us to ponder. Lets say you have an airplane and you put it in the dryer and run the dryer at a speed that would create enough lift to fly the plane would it do barrel rolls all the time or just sit hovering in the middle of the surround air?

Well what if the dryer were located in an international airport which had an entire runway that was a treadmill whose only purpose was to inhibit aircraft from taking off? Perhaps the dryer was aboard an actual functioning aircraft in mid flight and perhaps that air craft was transporting helium filled balloons now lets say all the avionics were calibrated to the China International airport but was descending into Denver International will the airplane try to land upside down? Will it succeed? As you can see this myth runs very deep down the rabbit hole.
I can't wait until MythBusters airs the results to this long discussed discussion.
Originally posted by TK: Here's how I look at it. Pick up a plane and spin the wheels by hand. Does it fly out of your hand? No. No amount of spinning will make it fly.
TK, I'm trying to figure out exactly what spinning the wheels has to do with the A/C flying? Please elaborate.
GOOD GOD!! ARE YOU LOT STILL ARGUING????????? THE PLANE WILL FLY!!!!! jUST TAKE A SMALL % LONGER THAN NORMAL, DUE TO THE EXTRA DRAG COEFFICIENT CAUSED BY THE WHEELS HAVING TO TURN QUICKER!!! Bwahahahahahah!!! Nick

Nick, As I asked my kids when they were young, please use your quiet voice. Thank you.

Actually, I am wrong, in a way !! It wouldn´t take longer to take off, just a %more thrust than normal, to counteract the drag from the wheels!! Nick
Originally posted by Formula88: Yeah, but at least the treadmill could stop a train.
Well now, is that train running with or against the direction of travel of the treadmill or is it running perpundicular to the direction of travel of the treadmill? It does make a difference. What voltage treadmill is it? Many things to consider, just as the commercial says, it takes a lot to stop a Trane.
