Here is a link to a KML file for google earth with the flight path.

FAR101 Governs unmanned balloons. So long as your payload is pretty small (under 4lbs) the rules are pretty easy to follow.
This is great, I'd like to see more of these. Could you geotag the launch site?
Wow, I think I feel a new hobby coming on...
Sadly I was left a little gutted when I looked at the weblink....somehow in my mind I conjured up images of a manned high altitude balloon adventure with sealed capsule and special suits....oh well...I really thought this was a once in a lifetime synth....
Anyway the photos are excellent!!
