If we really want to split hairs, that's not an Mi-8 in the above photo - it's an Mi-17. But I digress.
Looking at it strictly from the standpoint of a dude who's been doing rotary wing ops since 1982, (Parachute jumps, fast rope, rappeling, and helocasting into the North Sea) and still does, here are my thoughts:
The pilot is not very likely to have intentionally brought the aircraft into that attitude, but with updrafts, especially on uneven terrain, it could certainly shift into that position momentarily. One only has to read the crash reports of Chinooks in Afghanistan. And they're VERY stable due to the dual main rotors.If they can do it, any helo can.
Anyone else here ever jumped from a Huey? The violent rocking side to side as you slide off the floor? Sometimes I felt like I was going to fall out before the "Go" command. It can certainly happen with a couple of Muldoons jumping off of one side and then the other.
That question from Zero Dark Thirty rings true: Anyone here not been in a helo crash? Hard landings, falls, any number of unanticipated events - all part of the game. I don't find the height extreme (witness the Mi-17 photo) as a combat loaded parachute landing is like jumping off the roof of your house, and I've jumped from that height or higher myself. We all have. That's why every retired SF dude I know is on 100% disabiity.
After all that, all I can say is, I'd like to see better quality photos.
