This five-day-old Swedish skydiving video is terrific, perhaps even legendary, up until 1:31, which is when the GoPro camera flies off the guy’s head and it starts spinning faster than a light-speed clothes dryer for about 3000 meters (a little less than two miles) straight down. I’d been told that this video was a serious mindblower. Half of it is tedious. If only GoPro cameras had, say, little gliding wings that would automatically pop out and stabilize the camera when exposed to unnatural turbulence. The camera didn’t survive the fall but the memory card was intact.
