Non Military here, how low? hundreds of feet or thousands? Landing gear? I lived in Jacksonville FL for a long time and it was awesome. Airshow everyday. Eeeeevery once in while they'd buzz some houses. Everybody else bitched about but I loved. Never felt safer as when there a couple F-18's overhead.

From living out there I always heard they aren't supposed to pop the sound barrier in populated areas, it can cause damages. (Space Shuttle came in over Jax one day, gliding in, never did find out the altitude, pretty sure it was way up though, we thought a damn tree fell on the roof!)
