Yes, you got caught in that trap. That is the trap for the people who think of a plane as a winged car.
No, that's what I mean. Like I said, I took the conveyor belt to be a way of saying "the plane is stationary on the ground". So the engines are at full force, but the plane isn't moving forward. That's how I (and many others) interpreted the question and in THAT scenario, the plane definitely would not take off.
The people who understood that a plane was not a winged car knew that the plane would go forward.
