Hey all! I'm writing a proximity flying game as a side project (not the first that's been written, I'll grant, but a fun challenge) and am working on the physics engine. I've got a pretty sweet, simple aerodynamic model built, and the qualitative behaviour is all good.

My model predicts that a suitably skilled jumper (with wingsuit) exiting from the top of a 100 m cliff should be just fine to clear a sustained 3:1 scree slope at the base of the cliff.

I'd really hate to put out a game with inaccurate physics, so I figure an empirical test is in order. If somebody could replicate the above jump, and share video of themselves wingsuiting a 100 m cliff and managing a sustained flight over a 3:1 runout, I'll make sure you get a free copy of the game when it comes out.

Thanks a bunch.

 
Call the french men. They probable have it on there camera right now!

Having done a 100m jump, I have no idea why wearing a wingsuit would be a good idea from that height. You jump, pitch, and are under canopy within 3 seconds and then have about a 9 second canopy flight. You wouldn't get into flight and you'd have a fun time trying to avoid obstacles and land while you're trying to get your arms unzipped.

I seem to remember Jokke and Halvor doing a 4 second rock drop (240ft exit point) a while back.
