This was cool!

What is it? Its a space shuttle booster engine being tested, tonight out at ATK Thiokol, near Promontory, Utah. I heard about this from Noah last night, so the BSU and I drove out to see it after work tonight. Of course, a few thousand other folks heard about the motor test and drove out there tonight too! Night time tests are pretty rare so that explains the traffic jam on a road that is usually nearly deserted.

We didn't get there in time to get around to the front side of the mountain, so this little film clip is from the back side. It was very impressive! You can see more about tonight's test on KSL News' website.
