My childhood home was in the flight path for NASA when they were given the Blackbird after it's official retirement. We also routinely had fire-retardant bombers flying eye level close enough you could read the tail numbers off with a naked eye (we were on the side of a mountain, bombers flew down the valley).

Point is: the Blackbird, flying at altitude, sounded like a tree fell on the house . Big crash/thud suddenly. The bombers, though loud, were a steady build up until they passed, then quietly faded away. The Blackbird, I literally remember leaving the house to make sure there wasn't a hole in the wall or roof.
