Let's not forget, that but for the grace... The a/c could well have gotten there on its own (technical problems beyond his or its ken? ). Cuts both ways, seems to me.
The unknown is by its very nature, the unknown. To train for it is an oxymoron, and a waste of time. But let's be honest, and speculate to include the a/c as possibly the problem, No?
Thank you both for your patience
