Of course the plane is technically going forward because its wheels are moving but it isn't actually going foward horizontally.
This is what is assumed initially, but it is a false assumption. If it were correct, the plane would not fly. If the plane were going 25mph one way and the conveyor belt when the other way at 25mph, the plane would move forward at 25mph. Which is why it flys.
Adam is dead on. No one is saying that it could never get off the ground going against a conveyor belt at all. If it's going fast enough to
overcome the treadmill, of course it can get off the ground. However, the popular myth and the whole basis of the argument -- which the two dorks did NOT test -- is whether or not the plane can fly if the plane's forward thrust is only enough to compensate for the opposite thrust of the conveyor. As you just said, that plane could not fly.

Is this mercy-killing or cross-pollenation?
Only the strawberry knows.
