Featherweight Tracker - Balloon - 90K Feet - 20 Satellites - all good...

[kjs]

Here's a screen shot from a user that launched a tracker on a balloon. I'll post more info if I get permission (and hope to get phone log of flight to convert to KML) but nice to know that at 90k feet, the Featherweight still has good GPS lock and transmission back to the ground station. Note that this screen shot came from them still ~10 miles away 'as the crow flies'.
