I was at an airshow here when i was a kid at fairyhouse racecourse, there was an RAF Phantom doing a display at it. It did a mach 1+ lowpass at about 50 feet! Afterwards it was on the news that it broke windows around the area! Apparently there was bit of a mixup, the pilot was told not to go lower that 50 meters, not 50 feet.
It's something I'll remember till the end of my days.
