The 2007 Balloon mission was technically a failure, since we recovered none of the science nor tracking module. The tracking module failed shortly after lift-off (almost immediately as a matter of fact). We were able to follow it visually for quite some time, we think almost to the top, but once the balloon burst there was no way we could see the small parachute that it rode back down on. After additional analysis and running the weather on the Balloon Tracking program, there is a high probablility that the 2007 mission is located near the 'Estimated Landing Site' noted in the statistics below.
