This is one of the first things I've seen that actually offers a credible reason for the vanishing airliner... no, it doesn't involve aliens or trans-dimensional portals, which makes it a little less exciting than some of what's been floating around.

"Aviation investigators and national security officials believe the plane flew for a total of five hours based on data automatically downloaded and sent to the ground from the Boeing Co 777's engines as part of a routine maintenance and monitoring programme"
"As part of its maintenance agreements, Malaysia Airlines transmits its engine data live to Rolls-Royce for analysis. The system compiles data from inside the 777's two Trent 800 engines and transmits snapshots of performance, as well as the altitude and speed of the jet."
"A total flight time of five hours after departing Kuala Lumpur means the Boeing 777 could have continued for an additional distance of about 2,200 nautical miles, reaching points as far as the Indian Ocean, the border of Pakistan or even the Arabian Sea, based on the jet's cruising speed."
