The chase car behind the Blackbird with wind speed meters at several height levels all showing that they were going way faster than the wind should be enough proof.

You want proof because you fail to grasp the mechanics of this car. If you understood them then you would know it can work, and should work if constructed correctly.

Your fluid dynamics video is not based on the same principle as what is at work here. I don't know why you think it is.

It is a bit like trying to explain the mechanism of natural selection to someone who believes the species are created by God and immutable. No proof would be good enough, while those who understand the logic behind natural selection don't need proof. They rather predict what may happen in certain situations and will only run experiments to confirm what they understand.
