Condolences to Geoffrey's family and all who knew him.
I knew Geoffrey quite well, having flown with him at Rainbow Valley and other Phoenix locations since joining SSS and meeting him in summer 2006. A great guy all around to be sure and truly a "rocketeer's rocketeer" if that makes any sense. We often were the last ones out of Rainbow Valley during our monthly launches just so we could throw as many rockets up as we could.
Although I've drifted away from rocketry somewhat (but I've starting building again!!) I am thankful to have seen Geoffrey a few months ago at the SSS launch site at Salome Emergency Airfield, Arizona.
Rest In Peace Geoffrey, and may you always have clear skies, calm winds, and successful recovery of whatever you happen to launch.
