I wonder how loud a sonic boom from that high is at ground level.

I was visiting with a friend in the desert when Virgin Galactic made it's initial flight into space. I don't know how high they were when they passed overhead, but it certainly audible and rattled the garage door. Edit: after a quick search, the VSS Unity is released from the carrier at 50k feet. But now I can't recall if the boom was on the ascent or on the way back.

What I very vaguely remember, from an airshow at Edwards AFB commeorating the 50th anniversary of Chuck Yeager's 1947 flight in the X-1, is that it is clearly audible, but not so window-shakingly loud as when an F-16 went supersonic below 10,000 feet (which they weren't supposed to) where I live. (The latter happened several years ago during Thunderbirds practice.)

  I've heard a sonic boom out at Joshua Tree taking pictures at night. I thought a bomb went off until I saw the blur flying across the sky and figured out what it was.

Some of these incidents are probably false or exaggerated, but it does seem it produced enough of a boom to route away from cities.

Doesn't Brian Shul talk about the time Regan had them fly figure 8s over some foreign city during negotiations just to remind them with the sonic booms that we can touch them? https://youtu.be/3kIMTJRgyn0?t=1044 https://youtu.be/3kIMTJRgyn0?t=1044

  Yeah Nicaragua. They did it to Managua for years when they were also illegally arming the Contras.
