      Very cool.

      I’m starting to recognize the mountain passes in these videos.

    2. tyouth Says:

      That’s great.
      Wild guess: 80 to 100 MPH at those balloons. I wonder what the stall speed might be.

    3. Sev Says:

      there is also a good video of him jumping from a heli over the Matterhorn

      gotta think he’s going faster than 80 or even 100 mph.

      i’d like to do this. anyone know where it can be done?

      Sev – if I didn’t have a wife and kids and other responsibilities I would be right there along with you.

    5. Jonathan Says:

      I’ll bet that it doesn’t stall but that the sink rate increases rapidly the farther away you get from the optimal angle of attack. IOW there is little margin for error if you are close to the ground. I suspect that these guys choose their slopes carefully — too steep and there’s less of a thrill, too shallow and splat.

    6. Sev Says:

      Right that, Jonathan.
      And he was REALLY close to splat that time.

    7. Ken B. Says:

      Wow!! Got a rush just watching!!

    8. Bill Brandt Says:

      Is he the same guy doing those videos in the Alps? There was one guy that just flew by a group of onlookers at 120 or so.

      With his carbon fiber helmet he looked like a fly ;-)

      Sev – if this is taught I’ll bet students sign a good waiver ;-)

      I believe the location may be the Dolomites? Anyone know certainly where? . . . . Ah? . . . Might this qualify as a “low impact” sport?

      Sev, you can read a bit about wingsuits at wikipedia. My recollection is that many of the pioneers are dead due to flight incidents but it appears that wingsuit flying has now matured to the point of being only midly insane, with manufacturers of suits training and certifying instructors.

      To start: become an expert skydiver (recommendation: 200 jumps in 18 months). If you plan to do BASE wingsuit jumps, become expert in that as well.

    12. Sam Says:

      From poking around online:

      Wingsuit glide ratio: 2.5 to 1 (2.5 feet forward motion for 1 foot drop)
      Space Shuttle “the flying brick” at subsonic speeds: 4.5 to 1
      Parasail glide ratio: 6-10 to 1
      Hang glider glide ratio: 15-20 to 1

    13. Jonathan Says:

      There is a Popular Mechanics article about Jeb Corliss that gives additional technical information.

      Here is the Popular Mechanics article.

      Man that looks crazy

      He would have decapitated that guy with the balloons
