FLIGHT RECAP OF EOSS-31

On December 3rd, 2005 Mike Manes W5VSI provided a telemetry log file and some other information to help fill out this recap from zero information to a firm date, time of launch and burst and max altitude. However, the APRS/GPS system failed almost immediately during descent. So, no touchdown info is available. Still very sketchy on details. If you have something to offer to help fill this recap out, send it along to the webmaster.
