Document unexplained sonic boom like events on this thread

Well first, I hope I posted in the right place.

I've been hearing alot about single sonic boom like sounds that shake everything lately, and I think it would be a good idea to come up with a list of places where that has occured, and when.

I've been hearing about it happening in kentucy, california, and when I was on vacation in florida at the end of febuary 2009, I heard a loud noise, and everything shook.

It was a single boom; not a double ( like the space shuttle re-entry); and walls and windows shook.

People went outside asking what was that. My first thought was this has been happening lately worldwide.

People say it's the falling satelite, an explosion from the sun or behind it, or top secret planes? I don't know what I think but, I think it would be a good idea for people to note these events on this thread, with approximate dates and places.

Maybe it has been happening all over the world this year.
Maybe it's wide spread, or not.

Feel free to post anything you've heard or felt this year, and been unable to explain.

Good idea.

Marina Del Rey, Ca; July 2006. Was in apt 1/8 mile from Ocean at mid afternoon.

When all of a sudden there was a silent boom, shook everything and slammed many doors shut.
