yep. i was thinking how easy it would be to paint me as a political extremist if they wanted to - take a few selected posts from here and my facebook and i could be 'obsessed' with political injustice and economic inequality. it would be no less tenuous than what some rags have done in their portrayal of this pilot.
the 5000ft thing is interesting. i know it's not very rational and most have discounted it but i still have this nagging thing about dropping cargo or valued people and exiting the plane at agreed coordinates by blasting through the fuselage with a shoe bomb for example. do we know 'where' the plane was when it went to 40k feet and then down again or where it was that they think it dropped to 5k?
if the goal was a 9/11 style event i'd think the petronus towers a likely target and it would explain turning back but i don't see what could have gone so wrong that they'd end up flying south until running out of fuel and crashing into the sea. it would seem more likely in that scenario that someone shot them down but lots of reasons have been given as to how that is unlikely considering the resources being used searching and the levels of cooperation between various nations there'd have to be to cover it up.
landing anywhere seems unlikely and if you were heading to central asia i don't know why you'd turn back over malasian airspace.
if this is the intended outcome (for the plane to just disappear) then yes it would seem likely that's only effective in a wider plan of more events to follow (not using this plane) with say another flight disappearing or something as an ongoing demonstration of ability?
sorry - long thinking out loud.
