  1. Exactly. On an object where exit point is fixed (cliff with outcropping), you can simply look down and your guts will tell you all the math. In this particular case, he asks how high above outcropping he needs to climb to clear it. Math just shows that vertical safety margin is surprisingly sensitive to the horizontal one.

  2. Yo! To clear the platform of length L, assuming you're launching with horizontal speed V, you need to jump at least from height H = 0.5*g*(L/V)^2 above it. Here g is acceleration of gravity, g=32ft/s^2=9.8m/s^2. L should actually be the sum of platform length and half of your body height. E.g. for L=9ft (6ft platform + half your height) and V=8ft/s, H=0.5*32*(9/8)^2=20ft. Give it a good margin of error -- L=15ft (6ft clearance), V=3ft/s (weak poised launch) -- and you get a whopping H=400ft. Feel the danger now?

  4. Yo! It's easy to see from the sequence of pictures that you shook your hands while looking at the horizon before the launch. That's when the bridle got under your thumb. Don't shake your hand while the bridle is in it before the jump and you'll die during sex at age 100.

  5. Beautiful. Inspiring. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  6. Yo! Find someone with HC-1 and watch the footage on 34-50" HDTV. You'll have no more questions. Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  7. Yo! At 100 jumps, if you dedicate another ~20 jumps to tracking (learning objectives: WS-style exit, symmetric pull, angle of attack control, dealing with spin/instability/potato chipping), you'll fly Prodigy easily and safely. Prodigy IS prodigy, after all Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  8. That's f*cking impressive. Holding 1.5-1.9 glide ratio for 10 seconds is not just a momentary "flare". Care to explain body position and other details? Which GPS was used to record at 0.1s intervals? Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  9. Why bother with antenna? A tethered balloon will be much cheaper and safer. Heck, one can even have a cheap 'porta-BASE' -- a cluster of small balloons tethered to the car, like here: http://www.clusterballoon.org With some wind and rope long enough, there's no way to strike object other than Earth. While some can argue balloon jump is not a BASE jump, it's great for teaching students and making easy relaxed jumps. "What could possibly go wrong?"

  10. Yo! Good stuff , thanks for sharing. Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  11. The fact that the circular depression is centered at approximately D line attachment point suggests that it's simply tailgate at work. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  12. Agreed. It looks even scarier than the jump itself Bringing my Prodigy, let's flock
  13. I see tail inversion in the third picture... looks scary! A steering line could have ended up in front of the nose, making a lineover. Did you use primary stow? Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  14. Watch BASE videos by norwegian trackers. E.g. http://www.skydivingmovies.com/ver2/pafiledb.php?action=file&id=2882 These guys track so well because they want to live So learn from them. And aerodynamics says that the lower aspect ratio of the flying body, the lower the angle of attack for best glide. "Flat track" (about 45 degrees angle of attack) is too inefficient aerodynamically. Search BASE forum here and at blincmagazine.com for tracking tips from norwegians.

  15. Try (when you're ready, of course) flying just the leg wing (e.g., Prodigy's bottom half, or other wingsuit with wings disconnected and hidden under the shirt). You'll feel 100% free and will be amazed how much thrust you get. I'm getting horizontal speeds ~140mph and glide ratio 1.15, even without much experience. See attached track (1.95mi horizontally, 8800ft vertically in 50 seconds). Zooming at 140mph, especially when you pull at ~2K, is quite exciting Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  16. There are more than 6,000,000,000 Gods on Earth alone. Mine smiles when I jump. Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  17. That's because BASE = sex with the most beautiful woman out there: Mother Nature. Yuri Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  18. Yep, it is sometimes losing focus and regaining it relatively slow. Another glitch, it stops recording for a second on hard openings (e.g. 1s or more slider down BASE). No prob with slider up jumps. BUT.... I just watched the footage I shot at Bridge Day on 60" HTDV and the quality just blows my mind. It's simply unbelievable. So much detail... pixel to pixel. WOW! Also, this camera is completely free of purple fringing and vertical white stripe when shooting into the sun.
