The last time I was subjected to a "sonic boom" was at Edwards Air Force Base in southern California. They were doing the final acceptance testing of the FA-18 at the time.
I was standing in the museum of flight at the time it occured, and there were several Japanese tourists there. The building was steel skin/steel framed. It literally shook!
The Japanese tourists were screaming and looking for an exit. They thought it was an earthquake. I felt really sorry for them.
It is ironic that at the time, I was looking at an exhibit of a F-16 2 seat trainer. Anecdotal evidence would suggest that this "sonic event" was caused by a descending F-16.
