He also didn't seem to have thought about what would
happen if that chain snapped when under tension - i.e.
travel quite quickly through the space he was occupying.
That sort of chain doesn't do that.
Ah! It's the sort of chain that doesn't snap when stressed beyond it's
limits?
The sort that sees the links elongate long before they snap.
That sort of comealong just doesn't have the capacity to snap a chain
like that. The towing strap that is used to attach the comealong to the
tree would snap LONG before the chain ever does.
