On National Geographic Explorer this weekend, they did a bit with a skydiver who trained a falcon to jump with him, in an effort to determine the falcon’s top speed in a dive.
Anyway, on one of their bumpers to commercial, they claimed that a skydiver can’t breathe during freefall. They said it wasn’t necessary anyway, because the skin will absorb enough oxygen from the air. Furthermore, they claimed that the reason skydivers don’t jump on cloudy days is that the condensation on their skin would suffocate them.
This sounds like total B.S. to me. It sounds a lot like the Goldfinger “painted skin” myth. I imagine not jumping on cloudy days has more to do with seeing the ground than suffocation. Plus I know what water drops feel like on a motorcycle at 65 mph, they probably pack quite a sting at 120 mph. Any skydivers care to confirm/deny/comment?
