can the plane fly?

Under those conditions, no, the plane won't fly. Here is how the question should have been asked, and what the answer is. About halfway down the page. Sorry, I had to find the answer so I could sleep tonight. Unless I'm wrong.

nice, jim i think your the first person that understands the wording... and the qustion should only be asked like that if your want the anwser to be Logical

Actually the "question" asked by the question is what is irrelevant. If the aircraft creates enough thrust to overcome drag to achieve an airspeed that will create enough lift to overcome it's weight, it will take off . The real question is... what will the rotational speed of the wheels be at take-off and what will the motion and speed of the "belt" runway be at take off (this assumes the aircraft reaches that needed airspeed to take off). Everyone jumps to the conclusion that this is either irrelevant or that it will simply move as fast as the wheel turns . Since the question states that the belt is matching the wheel speed or RPM(which is zero at the start,assumption) the wheel RPM's at take off will be zero and the belt will be moving in the same direction as the aircraft at the same speed relative.



The question is so vague and lacking in information that I think there is no correct answer unless you make some assumptions.



1) You just throw out the runway/belt part without explanation (since the aircraft is setting on it I don't see this as a viable option)

2) You determine, by assumption, how the belt determines the speed of the wheels and what the starting point is.

Maybe that's why it's called a brain-teaser. Designed to keep people awake at night. :-laf

The original question does not state if power (thrust) is ever applied to the engines. If it is just sitting there with no power applied, it will not take off. The conveyor is irrelevant.

I had another idea that involved faster than light speed and destruction of the aircraft :-laf
