When it flys over SE Tennessee at Mach 1+ the shock wave knocks stuff off the walls of my hangar......
We had a big old cement bunker up on "Rocket Ridge" which overlooks the flightline and the dry lake bed. They used to test roickets engines up there.
When the planes would break mach 1, the walls of the bunker would visably flex. The first dozen times that it happened, it scared the bejezzes out of me. After that, I never even noticed it.
