I went on a tour on the USS Abraham when I was a kid in 89, and we got to see a Tomcat do a super sonic flyby at sea. It REALLY fricken loud. They told us there would be a super sonic pass at some point during the show but not when. Didn't even see it coming, the f14 came from behind the carrier so we never heard or saw it till it passed overhead supersonic.

Though they didn't do any low flying passes like in this video. The effect on the water looks cool as hell.
