Re: [Flyslow] Pin length and closing loops made from break cord

Moe V. showed me a rig when I was down in FL that instead of pins had cut away cable cut to about 3-4 inches attached to the same spots the pins would be. Orientation didn't seem to matter for extraction and there was in his opinion 0 chance for a container lock. I liked the idea for sure but haven't had a chance to build myself one yet. Busy with other side projects.
(And he probably claimed to have invented it, but) this is a version of the old 'Polish Pin'. When skydiving gear first went to hand deploy, before curved pins were developed, either a straight pin or even a bight of bridle was used through the closing loop, which sometimes resulted in a pilot chute in tow. Someone came up with the cutaway cable pin with a bungee closing loop and it worked pretty well. Moe's probably right, it probably would help with this problem.

Many years ago the world's leading BASE jumper (a guy with the oddly nordic sounding name of Boenish) actually contracted with a leading (skydiving) parachute rigger named Jim Handbury to create a rig that would have no chance of container lock, specifically for BASE jumping. The results were fairly impressive, in terms of creating a container with very minimal chance of container lock (basically zero chance if properly packed and closed). I wonder if looking at some of that research would be a place to start, if your goal is to eliminate container locks.
Ahh, the original velcro shrivel-flap containers. They worked great, and were prevalent for a long time (are they still?), but people worried whether they might blow open at terminal. If I remember correctly, I believe the aforementioned Moe V. made some airplane jumps with one (shhhh!) and went inverted, head down, sat, rolled, twisted, and otherwise TRIED to make it open prematurely, but was unable to do so. Replace the velcro often!.
