the plane wont take off. a plane works off the idea that the wings moving though air and the angle of the wings creats lift. ait moving over the wings is created by the jet pushing the plane forward. you can get the plane going as fast as u want, but thew fact of the matter is, it still takes air moving over the wings to take off.
heres i possibly the simplest way to prove this:
next time you are in your car at a stoplight, hold your hand out the window so its fat and your palm in parallel with the street. tilt your hand back. nothing happens. when you start moving, and are up to a decent speed, do the same thing, your hand wants to move upards.
