Something I've been really in to watching lately is investigations to airline accidents. I find the process of deduction and investigation fascinating!

I do wish it didn't often involve the loss of life, but I find it remarkably reassuring to know that in the incredibly rare chance anything would happen there would be a thorough investigation as to why and we could learn from it to prevent it from ever happening again. I feel this is an attitude more industries should learn from, putting the safety first.
