Is this the one Teeki?
A Startlingly Simple Theory About the Missing Malaysia Airlines Jet | Autopia | Wired.com

This would be the best theory I read. I liked it because it had no sinister claims in it.

I was thinking that perhaps it was hijacked and is somewhere like North Korea, a place who would not say they had the plane. That they have done all their Nuc/missile testing and now they are concentrating on other areas. If they are there I don't see a good outcome for them either. But could you imagine in 10 ears time all these people been released on day.

The ocean is huge and very very deep, I think the how can they lose a whole plain is an easy question to answer when you think of it. The harder question to answer obviously is how can you find a whole (if it is infact still whole) plane in such a vast area?
