Great story!
There is a reason why the SPOT is one of the best "balloon assurance" systems out there. Doesn't do much during flight but great on the ground :-)
BTW, thanks so much for the BS2 code. Will try to make it work here.

Crowded Air space today over PA!
Saturday morning, launched the Naval Academy Balloon (W3ADO-11) from Harpers FY and noticed two other balloons launched about the same time (W3EAX-9 and 11) about 40 miles north. All was going fine until...
Our sincere apologies to MD, VA, PA, DE and NJ! At about 3000' our balloon Arduino processor got stuck in a reset-loop and switched from 1 minute rate to one packet as fast as it could re-boot. Less than every 2 seconds! Fortunately they were direct only and at 100 millliwatts.
Fortunately, we could still see some packets from the W3EAX balloons, and APRS.FI seems to have copied them all.
Then ours went nuts! and appears to have come down very fast, and we raced to towards the impact point (20 miles away), but then 20m later, we got one packet at 38,000 feet 20 miles farther east. Then another race though Amish country and to our horror, the last position report was within 0.1 mile of the river and still at 2000 feet and heading right out to the middle!
We were about to give up the search (no more packets heard and river current pretty swift) when our back up system (SPOT system?) gave another report about 60 feet from the water. Low an behold, there it was, 60 feet from waters edge after having flown almost 100 miles.
Everything intact includeing HDTV video camera!
Apparently the students used a non-high-altitide GPS and it went squirrely until it got back below 38,000 feet. But you should see the track (W3ADO-11)
