If a parachute happens to land upside down, it should collapse and the pilot should dismount (possibly with injuries).

A parachute that lands upside down "bounces" until the pilot comes close to the ground. This can take some time.

Please run attached demo mission. A trigger turns the player's parachute upside down automatically when it gets close to the ground.

Bug is difficult to reliably reproduce naturally in game due to random parachute physics, but it does happen. The scripted demo mission shows a worst case scenario (parachute up vector 0,0,-1).

Bug tested in OA beta 1.52.72716 (but has existed since at least ArmA1)

Would be great to see this fixed indeed.

Not sure why your parachute would be upside down :P But I see/experience this almost every time I parachute and land on anything except a flat surface, sometimes even getting killed because of all of the bouncing/throwing when landing on a mountain.

Also can happen when a parachutist lands with a tall cliff just behind them - the collapse animation (which collapses downwards & rearwards) throws the parachutist upwards, causing the parachute to re-open, pilot lands, parachute collapses, throws the parachutist into the air again, rinse repeat ad infinitum.

Maybe the quickest and easiest solution would be to remove the collision LOD of the parachute entirely? thus the parachutist still makes it to the ground on first contact, and besides, if a parachute were to hit the ground first IRL it would yield to the ground anyway, not suddenly pull the user in any direction (or hold them off the ground like a solid object)
