(Boring unfunny post alert)
The pilot of flight MH370 was a supporter of a recently arrested Malaysian opposition politician.
This arrest and conviction on trumped-up sodomy charges occurred shortly before forthcoming elections, which no-one seems to have mentioned. I predict that it will eventually be established that pilot tried to hijack his own 'plane as a protest, probably planning to land at an unofficial destination, in order to generate international publicity about what he doubtless regarded as this outrage / scandal.
And that, after diverting the airliner, he was attacked by the co-pilot or others. In the ensuing struggle, the airliner decended, depressureised and continued flying on an unplanned course with a disabled / unconcious crew and passengers until it ran out of fuel.
Despite this story appearing in the Daily Mail I believe it is correct since it fits all the known facts and explains the suspicions surrounding the consistent lack of "full and frank" disclosure by the Malaysian authorities of, among many other things, what they found at the pilot's home.
I bet a NewsBiscuit mug that this will eventually turn out to be the case, notwithstanding attempts by the embarrassed / corrupt Malaysian authorities to hide / mislead people about the facts.
You read it here first, folks. Well, except for the Daily Mail, but unlike NewsBiscuit, no-one believes that or takes it seriously.
