"When asked why he fucked up, he became hostile." I don't really like little internet cutesies like 'lol', but literally, I laughed out loud at that.

I found a significant answer. All the involved numbers are on 'document 2', part 'E', outlined in red, in Shutter's post #5975 on the previous page. Describing the back chute found on the plane, it lists Pioneer, 26 foot, 226. and 9/57. I seems to mix up type, SN, and DOM, though. (Those numbers are also on the packing card shown in Bruce's photos.) Doc 2 also describes that 'other' canopy, an 'integral part' of the same rig, and lists Steinthal, 24 foot, 60-9707, and 7/60. It also seems to mix up type, SN, and DOM. Those are the two sets of numbers Flyjack has, seemingly describing different rigs. That second 'canopy', the Steinthal, 24 foot, 60-9707, 7/60, that has to be the pilot chute, and the size misread or typo'd as feet, when it would really be inches. There's just no other possibility in that description. There was no rig at that time, certainly not an emergency bailout rig, that had two full size canopies in one backpack. But a pilot chute could certainly be described as an 'integral part' of the rig. Those pilot chute numbers don't seem to appear on the packing card (Bruce's photos seem to show both sides), and they wouldn't reasonably be anywhere else on the rig, so to get those they must have opened the rig and read it directly from the PC.
So from that, it would seem that all those numbers are indeed from the same rig, that it was the one left on the plane, and it was the one they gave back to Hayden. See what you find when you read this shit in the middle of the night?
