I used to jump with Raul Torres and Betty Hawkins when I was stationed in Germany in 78-80. We did some crew, I had a GQ Unit at the time, but got my 4-stack (2130) in Schwabish Hall FRG in 1982!! I think I was on a Cruise Air at the time.
I used to jump with all of those guys at Pope Valley in the late 70's. Sparky and I did a lot of skiing together in the 80's. The last time I saw him was about 96 or 97 when I ran into him and his girlfriend Pat at the Reno Air Races.
As far I as I know Sparky still lives in the Bay Area. His first name I Kent if that's any help. Pat has a Cessna 172 so if you want I can go through my friend Jim Casper (old Yolo jump pilot) to see if he has heard from either one of them.
Even in the Bay Area the private pilot community is small enough that Jim can probably find them.
