Place OL-8. Time a tdy from Beale. How do I know it was SR71 tail #97x? Well they dumped fuel as they flew over and we could see the fuel trail but not the aircraft, so time later the soft boom (actually two closely spaced booms or so it seemed). It has been too long to me to remember the details, but I seem to recall it was a "training" flight that also celebrate a milestone and a large stuffed Snoopy went along with the RSO. I was off at the time, I was on the night shift and didn't meet the aircraft when it returned, but I do remember seeing a picture of the Pilot and RSO with a large Snoopy dog. People in western Colorado complain about the sonic booms from SR's but I believe those are from tanking operations. The alt records fo the SR are about 82000 feet as I recall. The speed is above mach 3. My Coffee cups have a big 3+ on them. I would sure like to get more. I got the ones I still have from the tech rep's building at Beale, $0.40 each, I said it's been a long time Jim Jackson (Former USAF Tsgt. Electronic sensor repairman)
