Statistics are useless - even if I calculate that I have a 1:1.000.000 chance that I'll have an engine failure tomorrow, nobody can't say with absolute certainty that I will have it or that I won't have it. The best ones are "flying is safer than driving" - there are too many factors, most of which aren't accounted for when people make "reliable statistics". It's like lottery - you have one in couple of million chances that you get the main award, but still - you could go betting every day for the rest of your life without earning a dime and some lucky bastard will win billions the first time he buys a ticket.
I too support The Killing Zone, very good book with many accident/incident reports combined with detailed analysis of each one. But basically, you only have to learn one simple word: NO. If weather isn't good, if aircraft has some inoperative item that you consider must-have, if you're tired/late, or if your gut says something isn't right - say NO and stay on the ground or away from specific threat. The moment you don't say no when you think you should, you've passed through hole in the first layer of swiss cheese sandwich.
