I shouldn't have to say it, but I'm going to anyways — do not try to jump off a building while on fire.
Now that the customary "don't be an idiot" PSA is out of the way, this video is insane. A Russian stuntman jumped 30 meters (about 100 feet) off a building while on fire. Pulling off his best Assassin's Creed Leap of Faith impersonation, the guy went back first into a pile of snow. He wasn't even using a stunt air bag.
From what I can tell, this wasn't for a movie or anything. As soon as he hits the snow, and black smoke curls out from the frosty embankment, people rush to see if he's ok. You think for a second he's about to get arrested for his little display, but then he's immediately interviewed about the experience. I can't tell if this guy is a hero or just completely crazy. Maybe both.
Strangely, the whole jumping-off-buildings-on-fire thing is a sort of Russian pastime. Sploid posted a similar video last February though it seems these high divers have upgraded their aerial antics with a head-mounted GoPro this time around.
