Grimmrad, a very good question ! I think the answer should be roughly as follows, like someone in your profesion who bends his car on the way to the hospital to cut someone up, a pilot, like a doctor, should be able to seperate the incident from what he has to do next, most can I belive, some cultures have a problem doing this, there lies the problem. A little story from my past, we were waiting to go at a Canadian airport when tower let us know that the flight ahead of us had dived veritically into the ground with no hope of anyone walking away from that one, they then asked us if we still wanted to take of, I remember the collective spoken comments between the three of us was why the hell wouldnt we go? Like your job one has to seperate things and handle them at the right time, in this case after our flight was over and we were enjoying a good meal and a glass of very fine German beer!
