The US gov't will be monitoring it, All this searching lark now is just a delay. It has followed another plane in the same path west of Malasia (Two planes within 500ft of eachother at ATC will show as one dot on the radar, not two dots), this plane had it's transponder on, so allowed the 777 to follow undetected & un-questioned. I wonder what else will follow. USA know more then they are letting on. Malasia are letting on more then they know. (i.e In a press release saying that the plane was 100% hijacked, and 1 hour later _denying_ they even said it was hijacked...WTF) It is also confirmed that the "All right, good night" message was the co-pilot.
