I can't say with absolute certainty that there has never been a manned hypersonic demonstrator because certain sources have insisted that there was one. On the other hand, I have never found any evidence, circumstantial or otherwise, for such a program.

The "donuts-on-a-rope" contrail stories are nonsense. They were just ordinary contrails with typical subsidence puffs.

The sky quakes were real. I cannot dispute that because I experienced one myself in the early 1990s. My father felt it, too. We thought it was an earthquake, at first, until were heard more about it on the news later. No seismic activity detected. There have been suggested explanations for "sky quakes" that do not involve hypersonics. I have no way to evaluate these explanations.
