Friday Night's "Earthquake"

Friday night I was jogging at the beach. Beautiful sunset. Moon hovering low over the orange glow. All of a sudden I heard what sounded and felt like thunder. There were no significant clouds around. Turns out it was 2 F-18s that broke the sound barrier while flying in from Pensacola. It registered 2.7 on the Richter scale and could be felt throughout West Central Florida.
