  From the transcript: the system did trigger and the system did send the signal and the air cylinder did activate but in the split second while all this was going on the area between the two was compromised so now the levers are so much closer than when the cylinder activated... it didn't pull far enough to get the parachute wires to come out of the pack. So it seems that a structural failure or deformation of the vehicle rendered the release mechanism ineffective (had it collided with something at this point?) This seems to imply that the cable was not in a sheath, and I suppose there are arguments either way as to whether sheathed or unsheathed cables (or rigid rods) are the best way to go.

    Sheathes are weight. Maybe it was deemed less important before this accident, and now we know better. This is exactly how industries advance.
