If it’s a trick on words, fair enough; but lift generated is directly proportional to the square of the wing’s velocity relative to the air around it, so that’s all that matters; how fast is the wing moving through the air. If the conveyor’s like a treadmill so it isn’t moving relative to the air (as in rolling forwards) it won’t fly. If you had a 200mph wind screaming down a runway, then a jet could face into that, and fly quite happily.

Considering the plane doesn't actually move relative to the ground and through the air, there's no actual airflow underneath the wings. Thus, there will be no lift. Ergo, that shit won't fly.
