The one thing that comes home to me both for this and the 146 accident is that in both cases it looks like "they had done it before and got away with it".
If (private pilot but flying glider tugs) I have ever done anything once and got away with it then I would try to avoid ever going there again.
So what is it in this Colombian context- Greed, the shear economic need to do so to stay alive (personal economics or for the airline) or some strong machismo belief that "I will continue to get away with it". Any comments in a local context please?
