Flight #10 - 2004b

This will be a fairly simple flight primarily used to test the latest version of Balloon Finder before GPSL. The primary goal for this flight is to test the time-slotting capability of the APRS controller board and to freshen up the flight crews before the Super Launch.

Because of the late launch times, we will be flying a small payload on a large balloon in order to expedite the flight. We are expecting a total flight time of approximatly 1.7 hours.
