You know how cyclists can get those rollers that they can use indoors to train on when it's raining?
Well, this treadmill thing is the same concept really in some ways. If planes were able to take off simply by the thrust created by engines from the treadmill, doesn't it stand to reason that airports would create some kind of giant set of rollers so they don't need long runways?
