If someone deliberately switched off the aircraft transponder, presumably they weren't aware that the Rolls Royce engine data transmitter would continue chattering away to its makers. If true, then another 4-5 hours of engine usage after disappearance is really quite extraordinary.
And for the US to mention the word "Hostages" whatever has really happened may well be being covered up, the co pilot allows people onto the flight deck, the engines continued to chat to the servers for a further 4 hours, if and its a big if, this is all true and not journalist speculation, then there is a big chance the plan has landed at a location with a runway long enough for a 777 200 ER (the ER means extended range) if it is full of fuel it could fly half way around the world..........crashed hundreds, maybe thousands of miles off course, possibly, also landed in Iran, another possibility, how long would the flight to Iran take? 4 hours.
