That's an interesting idea. The first three out of the East coast sequenced but then broke down after that.

Oh well, just a thought about the *Booms*.
We had some about 20 or so years ago, always around 7AM to 9AM.
Would shake the house or I could hear them in the truck while driving to work.
Sounded like they came from the south (Gulf). It went on for a couple of weeks, pretty regular, always figured it was jets breaking the sound barrier over the gulf.
Probably out of Keesler AFB or the New Orleans Naval Air Station.
Would be heard from the Thibodaux, Houma and LaRose areas.
When we would get to work in the break room having coffee, someone would always ask, "Did you hear the booms" and just about everybody did.
Always figure they were sonic booms, had that *double rap* characteristic.
