Click that for a scary theory. Tl;dr? Shah steals plane with full fuel tanks, flies around pretending to ditch in sea but actually goes on to friendly radical Islamic country. The 777, one of 1000 in the world, now has the capability to appear as if it actually is ANY ONE of the 1000 in the world. Such as a flight from Mumbai to London. Camouflaged as such, it can fly unhindered to London (because authorities would see it as the real Mumbai flight) and dump a shitload of chemical/whatever weapons in the middle of London town, suicide stylee.
Sweet dreams.
Haven't read what everyone said but I'm going with a simple 'it crashed off the radar'. Incidents happen where black boxes aren't picked up for whatever reason once in a while. Don't remember the name of the plane but back in 2007 an Air France jet crashed in the Atlantic and they had no clue what happened for months - didn't even find the actual plane until 2011 because the waters were so deep. I highly doubt anything different's happened this time.
A new report circulating in the Kremlin today prepared by the Main Intelligence Directorate of the General Staff of the Armed Forces (GRU) states that Aerospace Defence Forces (VKO) experts remain “puzzled” as to why the United States Navy “captured and then diverted” a Malaysia Airlines civilian aircraft from its intended flight-path to their vast and highly-secretive Indian Ocean base located on the Diego Garcia atoll.
