(UPDATE: Chris says: "One tiny correction on your Boing Boing post: we don't use a compass.
We use GPS for navigation, three-axis thermopiles (glorified IR
sensors) for stabilization and a differential pressure sensor for
airspeed control.")
Second place went to Team Mookemobile for their Deathpod 3000, which was the only other vehicle (out of 15 in the race) that made it around the entire course.
I'm writing an article about the exciting event for a future issue of MAKE, and you can be sure I'll let you know as soon as it's in print.
