I doubt much will come of this, but just curious if anyone has experienced/has any thoughts on what happened to me.
After a normal freefall, I was under a good main by 4300 feet; but noticed the reserve pc and bridle was out. Reserve bridle was wrapped around the main risers in front of me from right to left (importantly, i think the pull force was toward the front because of the way the bridle was wrapped, keeping the reserve freebag in the container...i'm a lucky motherfucker). I reeled as much of the PC/bridle in as i could and made it back without further incident. When i touched down, I felt the reserve/bag pop out of the container and lay on the ground next to me.
So the reserve pin popped right? The odd thing is that the rigger's seal on the reserve pin was somehow unbroken. the closing loop was fine. the reserve/cutaway handles were seated and everything in place. before the jump, the pin was checked by the packer, by me, by an experienced jumper on the ground, and again by a coach at ~10,000 feet and looked ok.
Seems to me that the reserve deployed as the main was coming out (it probably wasnt out in freefall cause then i'd have been riding a reserve down from up high; plus the reserve bridle wrapping around the front side of main risers suggests the bridle wasn't stretched out behind me as the main came out...i think...).
anyway, i'm just trying to wrap my mind around how this happened for the sake of not repeating it. I'm a student so could well have unknowingly done something dumb..e.g. bump reserve pin on the way out the door...but didnt feel anything like that. best we could come up with is that the pin got bumped/otherwise moved and then when the main deployed, it was just enough to pop the pin. seriously curious how the rigger's seal didn't break. the only thing that i didnt look at afterwards was if the container itself was somehow damaged near the pin, but that seems unlikely. any ideas?
