"There is probably a significant likelihood" that the aircraft is now on the bottom of the Indian Ocean, the official said, citing information Malaysia has shared with the United States."

Why would anyone hijack a 777, fly it 1/5 of the way around the world and crash it in the Indian Ocean?

WE don’t know who was in command of this flight, but we do know that he knows how to fly a 777 so it is not likely that he ran out of fuel over the ocean.

No nutcase gun slinger would even know how to turn off two transponders, much less manage the fuel systems, etc., for 5 hours.

One of the crew was involved and the Malaysian government or someone within the government was/is involved.

Again, who were the Chinese on board?
