Topic: Mysterious sonic booms
I live in Florida, the space shuttle lands a lot, or at least it used to. However, every so often I hear these loud booms that shake the house. I don't know why they happen. I've heard them during re-entry of course, but I hear them a lot during other times. They sound like something exploding, except there is no explosion, not even a blast of air just sound. In fact I heard one an hour or so ago. There are two variations, one that is just one loud boom, and another one that is two successive booms, with a sort of echo to it. I'm trying to rule out anything alien at this point. It's just one of those little things I can't put my finger on and it bugs the crap out of me. Is it some sort of test craft? Satelite launches I don't know about? Any ideas?
