BBC News - Missing Malaysia plane: 10 theories examined
Several references to "Forum" speculation.. beware the Journo's
Personally, I am still struggling with the concept that in this day and age, 247 Tonnes of mixed metals travelling at 500 Kts can just vanish without a trace.. The whole thing stinks in terms of lack of a cohesive multi national SAR mission, lots of politics, agendas and reluctance to divulge info.
In terms of speculation and conspiracy theories, well who would have thought that a bunch of folks would hijack a few planes and fly into skyscrapers in the USA?? Nothing would surprise me here.
