http://www.x-tremevideo.com/ A group of engineers/designers from San Francisco made the balloon launch on 6/5/2010. Shot with 2 HD Hero cameras from GoPro. Launched from the California coast near Davenport, landed in Crows Landing 70 miles away. Peak altitude 80,000 feet. Acquired GPS, pressure, accelerometer, and temperature data with a Shadowbox (shadowboxlive.com). A big thank you to Kevin Macko for the great footage!
