"Because pilots tend to be macho Alpha males subject to all the ills of testosterone, including poor judgement and a tendancy towards breaking rules and living on the edge."

I find that insulting, offensive and sexist. I know plenty of pilots (both male and female actually) and I don't think that I would describe any of them as either of those things. Also, females have testosterone too. You might want to brush up on your biology before you make another bigoted statement.
