it would need control surfaces, however, which we would call "wings" due to the resemblance to the larger counterparts on ancient Earth relics called "aeroplanes." 
The point is, you could use lift to control the craft, even in the absence of gravity.

found this and I couldn't resist to revive this now defunct thread from 5 years ago . . . .it would not fly.
unless the wings are moving through the air there will be no lift created and the plane won't fly.
if the engines are drawing in air, compressing it, mixing it with jet fuel and burning the mixture, the result is a tremendous and continuous expansion of the gaseous mixture in the combustion and exhaust chambers of the engine. . . with the rapidly expanding gases having no where to go except out the back of the engine thrust is produced.
for the plane, this means that the the engine will want to go forward.
since it is attached to the plane, the plane also will want to go forward.
since the plane is attached to the wheels, they too will go forward.
the fact that the wheels are a conveyor moving in the opposite direction means that as the plane is "moving forward" the conveyor's moving backwards keeps the plane in the same spot.
which means the wings are not moving through the air.
which then means no lift is being generated
so the plane will not fly.

The wheels don't stop the plane from moving forward no matter what they are on. tunafish, ballbearings, asphalt. Doesn't matter. The plane will move forward over the conveyor no matter what speed it is going.
@ tunafish but it's true. thrust moves the object, not the wheels.

The plane will take off. End of story.
