As mentioned at Denny's last night: http://members.shaw.ca/sonde/index.htm I was talking about a self-guided glider someone designed to be launched at 85,000 ft from a weather balloon and a few people were intrigued. It has an on-board PC-104 form PC for guidance with GPS, temp sensors, packet radio modem, electronic compass, web cam and runs rom-dos. Lots of cool pictures and details. Brian Kelsay
