Is it possible to learn, from these sonic booms, something about the booms attributed to Aurora? J.

I don't think so--they flew over Dryden at a similar flight condition and it just sounded like any old boom from high altitude. Not very spiffy at all. My favorites are booms from low, fast aircraft, as these have a lot of high frequency content. Those of you who've been to Shuttle landings know what I mean, although the Shuttle boom isn't the best boom I ever hear (but I'm right under the medium-altitude supersonic corridor). If you know the airspeed and the altitude, you can use the profile of the overpressure to make an incredibly rough estimate of the size of the aircraft, if the altitude is low enough. But if you knew all that, you'd know how big the airplane is already. Remember that a sonic boom is just the shock--all it tells you is that there's something making a shock out ther.

We see lots of aircraft in patterns for the strip every day, mostly Tomcats and A-4 and F-16 aggressors. But today there was a stranger in the pattern. I had to look twice, but sure enough it was a pair of F-117's! I know people a the Top Gun school... I will see if I can find out what they are doing here.
