It's A Bird, It's A Plane, It's A...Guy On TOP Of A Plane?!

If you thought skydiving and BASE jumping was crazy, then wait until you get a load of "wing walking!" A daredevil by the name of Luke is demonstrating the stunt in this incredible clip, where he climbs on top of an airplane *while* it's flying. We can't decide if it's absolutely insane or bucket list material...or both!
