That particular 46 was 75 feet off the deck when it let loose. Think they were gonna do hook n haul drills. As far as 53’s, I can tell you from first-hand exerience (couple very hard landings) that tears are the last bodily function that comes up.
Most of the guys that I knew who got croaked did so via the shitter. The 46 synch shaft parted, from 75 ft all you can do is bottom the collective and crash. Aft head is still powered, forward isn’t. Where the blades mesh means that there will be problems.
