Yes I get that however regardless the plane has to get up to speed in order to take off to create lift, if the plane is stationary, like the way the mythbusters are going to be doing it, the plane will justsit there. The way they are testing it is that if thetreadmill is going the same speed as the planes take off speedthe plane will lift off without the plane its selfgetting up to speed in other words just the treadmill is moving and the plane is remaining in the same spot and is just fighting the drag.

Now if the planewas actuallytaking off andwhile thetreadmill is also going at the take off speed the plane would be able to take off, all it would have to do is match the drag of the treadmill and increase the speed because all the wheels free spinningare there to help it get up to speed. I'm not dooubting that it isn't paossible, BUT I doubt that it will take off the way they are testing the "myth".
