Lets face it this thing could have been caused by any number of things and have one of millions of root causes. On the matter of drivel I think its a matter of opinion. Maybe lets cut the KQ workers here some slack, remember they are shocked and angry and have just lost a bunch of friends in one go. Its understandable that they might drivel on a bit. To the rest of us drivelers well we have no excuse
Not to speculate at all but out of Douala the groound crews there would always try to sneak things on to the plane. They would get paid by the sender, maybe a few bucks, to do it and their compadres at the other end would pick up the goods. Saves the sender paying the higher prices to the airline. Very well organised scam to all destinations in the area. I am sure they put 'extras' on KQ and other aircraft as well. Industrious little blighters.
