"If a plane is traveling at takeoff speed on a conveyor belt, and the belt is matching that speed in the opposite direction, can the plane take off? "
If the plane needs to move 60mph for takeoff speed, and the conveyor moves 60mph in the opposite direction, as prescribed in the above statement, then the friction from the wheels might make the plane move only 55~57mph. The plane isn't going to just sit still like some people want to think.
The wheels are just attached with bearings, no gears, drivetrain, or anything that will actually truely effect the speed of the plane. They might as well be water ski's or ice ski's which a plane can take off wearing also.
I've posted this twice now and people still argue around me, but noone seems to refute this: A plane with wheels on a conveyor is the same as a plane with water ski's on water or ice ski's on ice. It will not just "sit" there. It will move forward at "almost" the same speed as if the conveyor was not there at all.
