I flew in Maun for a few years, a few years ago. I can say that, to the best of my knowledge, back then there was only one particular operator who used to place undue pressure on his pilots, out of 7 or 8 companies. Anybody who flew in Maun in the late nineties, early naughties, would know who I'm talking about.
It's not uncommon for young inexperienced pilots to feel under pressure when trying to get the job done. IMHO this pressure exists as much in their own heads as it does in the real world. My point being, there isn't enough emphasis in training on recognising safety margins and establishing no-go gates as there should be. Some operators exploit this.
I am not saying that this was a factor in this particular accident, merely responding the emerging theme of this thread which, I might add, is starting to sound a lot like the recent thread on accidents in SA.
