Skyliners Attempt Insane Hot Air Balloon Slackline Walk [VIDEO]

Watch these French daredevils who call themselves the Skyliners, walk a slackline strung between two hot air balloons. By the way, they're 10,000 feet in the air and aren't using safety harnesses.

I've seen people slacklining around Grand Junction, but this activity typically involves tying the line a few feet off the ground between two solid objects. If you lose your balance trying to walk across, you're close enough to the ground to land on your feet or fall without injury. That kind of slackline I would attempt.

With that said, I thought these daredevils were pretty bold until the end of the video where they say they're going to try it again. At that point, it was clear these guys are totally out of their mind.
