Their experiment confirmed our conclusion: that it had little to no effect on the plane's takeoff.

The only problem I had with their tests is that they didn't replicate the circumstances. In their small and large-scale tests, the plane was not matching the speed of the belt, did it? Otherwise it wouldn't move forward relative to the ground until it took off, right?

I'm sure I'm missing something.
