Very cool vid, Andy.
You're not pulling enough Gs to black out JoAnn. No different that travelling 100 mph in your car...... well, to a point
And it takes about 10-15 seconds to reach terminal velocity, slower than an elevator accelerating, so you don't feel the G force.
Certainly looks like fun. I imagine a lot of thought and planning goes into their glide path, since they are always decending. And of course it would be illegal where ever BASE jumping was not allowed. Not that that's ever stopped any Base jumpers
I had a winged suit of sorts, which allows a lot of control with your fall rate.
Back in "the day". About 10 years before skydivers started playing with those wing suits.
