It takes longer than a month to get your airside pass in Botswana - I did a fair stint in Botswana including Maun, all in all, the companies are fairly good - but you allways get a few clowns.
Just on what I have seen in the press - inflight FIRE rings bells! rumour 1 guy jumped out before it hit the ground & survivours say there were flames as well.
I don't believe that they will get an answer on this as there is no real answer on the in flight fire and crash of A2 -DBH crash that was seen by quite a few of us, that to was fatal!
