Things do actually change in the army airborne community albeit slower than macroevolution. I know that keeping a one arm interval with the jumper in front of you is much more strongly stressed now than it was back in the day if it was at all. This has probably increased the time needed for a pass and increased the red light chances. It’s a big deal when you are trying to get your night assistant jumpmaster duty done to get your star and there is only going to be one pass.
I only jumped a 141 in airborne school, and I’ve heard, though I’ve never confirmed or completely believed, that the vortices were far less thereby decreasing the likelihood of high altitude entanglements and making it possible to jump right on top of the guy in front of you. Not sure if I’d stake my life on that.
Me, I was always scared to death of a collision, and was probably more scared in general due to having a skydiving background before I ever started army jumping where you can plainly see people waving to you from their backyards on jump run. It was a great relief when I became a jumpmaster making it possible to go out last and avoid the swarm of 19 year old dirt darts flailing around in the dark with 60lb rucks, machineguns, tripods, mortar base plates, etc. Even as the assistant, I would wait till the PJ’s door was done before I went, usually with a good ‘2 count’ beforehand.
You gotta love how the army deals with accidents – mostly by making sure as few people as possible know about it. As some have already mentioned, the safety focus in the skydiving world is a wonderful thing where incidents have always been published, instantaneously now on the internet, and there is commercial incentive to improve gear.
Not long ago there was a legendary accident at Bragg involving a jumpmaster student. As I’m sure you all know, the reserve ripcord was on the right side of the pack. Now it’s in the middle with the handle pointing up. This particular student was executing a clear to the rear, and the side mounted handle caught on the door, activated his reserve, and pulled him up and out of the bird decapitating him in the process. So someone comes up with this $.10 plastic insert that goes underneath the handle when you’re doing a jumpmaster duty and supposedly makes it resistant to that kind of pressure. Problem solved! We can all sleep easy now!
Incidentally, the handle is now in the middle in the event your right hand is pinned or immobilized, and they added a spring operated pilot chute eliminating a lot of the old heroics required to operate it. Good ideas but should it have taken 50 years to come up with them? You’d have to be one bad mo-fo to be going in with a spinning or total malfunction under 800’ and be able to beat on your reserve, perhaps throw it in the proper direction, and god forbid, reel it back in for another attempt!! Also, the metal grommets that used to close the reserve have been replaced with a ‘soft loop’ system greatly reducing the likelihood of it jamming shut. You know, stuff that has been on civilian rigs since who knows when.
And then there was the whole inversion thing. How many people bit it over that? So they add a few inches of ‘anti-inversion netting’ to the bottom of the canopy. Good to go.
