I take one of those areas is NOT right by the airport. My work is directly next door to the FBO…where they planes are kept for the air show. The Thursday and Friday before the airshow they practice and there have been a few “sonic booms” during practice. Last year a f-22 raptor did it while flying like (what looked like) 20-30 feet above my building.
Edit: after watching a sonic boom on you tube and I didn’t “see” it…but it did make a big boom sound and shake the building???
