It is a reality that we face in aerial firefighting, you can make good decisions 99,000 times out of 10,000, but that one time can result in you being in a pile of wreckage on a hillside.
Its also a reality that people who enter this field, can be a bit more fiercely independent and strong willed, if we just wanted to be a faceless number on a seniority list we have chosen something else to do with our lives.
That being said however, getting acrimonious about this does no good at all, and probably not what Tom and Mike would be wanting out of fellow aerial firefighters. I would much rather honor what they did, learn from what happened, and endeavor to not repeat that kind of event, which has unfortunately happened much too often and cost the lives of some great people.
We are all human and we will sometimes have lapses in judgement. It can be tempting to give in to pressure from dispatchers, or maybe someone in ones personal life is going on. There was another crash a few years ago (mentioned in this thread I think) where a P-2 crashed into mountains. I am flying with someone who was a good friend of CD (no not Captain Dad) and said that CD was in the midst of a really nasty divorce, and he came this close to suggesting to him to sit on the ground for a while until its all done, over all all the personal issues from it. He still has some guilt over never getting around to making that suggestion.
All I can do, is just hope to learn from their mistakes, and not find a new one of my own to make.
