I cannot comment on your eye-sight, and have no desire to enter that dispute you are having above. It's just physics, especially knowing the "frame of reference" of kinetic energy and vectors. And no, my claim does not justify any of those "create energy out of thin air" theories, which a consider just bags of hot air.
Towards the example you gave above: I only held in a jet-stream once, and while the effects were not as extreme as your hyperbolic choice of words, in a gist you are correct. But that's because the FMS was trying to fly a fixed pattern over the ground. So that should not be relevant here. Or is it?
