What I don't understand is why someone would choose to undertake a dive that has zero room for error.
Maybe there was room for error. But when you prepare for something risky, you have to draw the line somewhere as far as how much contingency is practical. In incidents involving fatalities, the victims simply fell on the wrong side of the line.
That's what's difficult to swallow - knowing that they could have done more - but that's hindsight for you.
