i just want to clarify somehting that i think a few people arent understanding..
When some of us say the plane will take off, we do not mean it will go from a dead stop all of a sudden to being airborne. that is impossible, we all agree you need speed to be able to achieve lift. what we mean is that it will eventually take off. It will begin to move forward and accelerate, and once the speed needed for lift is reached it will then take off. Additionaly, if the plane will be on the treadmill up until the time of liftoff, the treadmill MUST be as long as a normal runway, not just the length of the plane, if that was the case, the plane would roll forward and off of it. i just wanted to say that since i think people are thinking of it as IF the plane will lift off right in the same spot where it started from. which it wont, but like i said eventually it will though.
