It's official. Everyone has now done the ALS Ice Bucket Challenge.

We did ours this week, following the trend of everyone dumping buckets of cold water on themselves to benefit ALS research.

This guy, race and aerobatic pilot Bruce Bohannon, wanted in on the action, too. And he upped the ante a bit with what may be one of the most death-defying Ice Bucket Challenges to date.

He did it while he was upside down in his stunt plane. Well done, Bruce!
