Video: The Balloon Highline

When climbing/BASE jumping pioneer Steph Davis says she loves something, as she just did about this video on Facebook, we’re instantly curious. “It’s so beautiful, so group-oriented, so technically demanding, so unique … so French!” Davis marveled in a follow-up email.

This may be a stunt, but we could not stop watching. And only realized we were holding our breath after the video was over. The feature film comes out this summer.
