This fire invites comparison to the Mann Gulch Fire which took the lives of twelve Smoke Jumpers. And this book invites comparison to Young Men and Fire - by Norman Maclean , the father of the author of this book. The books are different. I think it is a better book. We've seen this scenario before.
Little things go wrong, nothing to worry about.
But, seemingly against all odds, these little things accumulate, adding up to a disaster. We see it in nuclear power accidents. We see it in climbing Mt. Everest, or trekking to the South Pole. We see it in disasters on rocket launch pads. We forget that everything can go wrong at once.
