Agreed, probably a sonic boom, they can shake houses for miles.

I'd actually never heard one till I was fishing on a partyboat offshore of Maryland; got buzzed by an F-15 at VERY low altitude and he was supersonic.

I really never expected one to be THAT loud. It was behind me and I didn't know what it was till I turned around, almost crapped my pants and almost lost my rod in the water.
