It does seem like I am being a bit of a spoilsport here, and could be proved wrong, I don't actually think anyone will ever know what happened on this flight. I would be surprised if they managed to find much of the aircraft, if any. And even if they do, if it managed to fly for 7 hours before crashing the most useful part of the information in this case - why it turned off its course - would be lost anyway. The cockpit voice recorder records on a continuous loop, overwriting earlier recordings. Normally after a crash the cvr stops recording at that point, and it is possible to retrieve the info. Generally they record for 2 hrs.
There are lots of things that could have happened, but the more far-fetched the theory, the less likely it is to have happened. Wondering who is likely to profit, about the secret cargo, about political fallout - it's all a bit ridiculous. I've flown with a pilot who was on board a very famous flight, he ended up in a very precarious situation and was lucky to emerge from it. There were and still are a lot of conspiracy theories surrounding what happened on that flight. I asked him about it once. He was happy to tell me what happened to me, and was quick to put down any conspiracy theories. There was no ulterior motive, they were just in the wrong place at the wrong time. I'm not going to give away which flight I am referring to, so as not to out me or my colleague.
And if anyone is doubting my credentials....
