Copper could have checked the chutes, right? We know that he opened them at least partially, and then he had time alone after that.
He opened one of the reserves in order to scavenge lines. If he had opened one of Hayden's bailout rigs, unless he was a rigger and had rigging tools with him, it would be highly unlikely that he would have been able to re-close it suitably for use.
interesting point.
Then again
Assume whuffo. You need lines.
You have 4 rigs.
You are going to jump with one of them.
You apparently know that all 4 rigs have lines.
Which of the remaining 3 rigs do you open? You're not going to use any of them, so why would you pick one over another?
You could say "random"
Or you could say it was easier to open the reserve.
or you could say he was half-thinking maybe the reserve could hold the money and somehow attach to himself?
Or you could say he was a cheap jumper at his core, and couldn't bear to destroy a perfectly good back rig
i.e. destroy the older no-good reserves...almost an instinctual bias if not whuffo.
I mean, would a whuffo think the line length varied in reserve vs back rig? Me I'd guess the reserve had shorter lines.
Did it?
