Boom! Boom!

That's what I heard at 8:35pm.

At first, I thought it was the kids down the street shooting off fireworks over Lake Hammer.

Then, I realized the space shuttle Endeavor was due to land over at the cape.

For ye socks who live outside of this little corner of heaven, we get a window-shaking "heads-up" every time one of the shuttles comes in for a landing. The twin sonic booms happen when they break the sound barrier.

Pretty cool, huh?!
