Around 12:30 PM Friday, as I was sitting at the computer working on my latest indexing job, the house shook with two strong, closely spaced slams a fraction of a second apart. The dog started to bark and my wife, who had been napping on the living room couch, sat bolt upright and asked, "What the devil was that? Another earthquake?" I told her I thought it might have been a passing truck, but frankly I didn't believe it--the double bang was too loud and too sharp. I went out to see whether anything had fallen against or onto the house, but nothing was disturbed. I finally decided it was the neighbor moving his garbage cans back nito his driveway. But yesterday a local news report noted that STS-117, which landed at Edwards AFB a few hundred miles north of San Diego, had sent its re-entry sonic boom all across southern California, startling the citizenry (I guess it came in from the southwest). It's the first Shuttle sonic boom I've ever felt. ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
