Malaysian Prime Minister Najib Razak said Saturday that the plane bound for China was still flying at 8:11 AM, about seven hours after it took off from Kuala Lumpur and about half an hour after it was expected to land in Beijing. This last data point, from a satellite trying to communicate with the plane, indicates that the 777 was still in the air when it might have been running dangerously low on fuel, raising the possibility that a possible hijacking might have ended with a crash.

The precise location of the flight at 8:11 AM is still a mystery. But officials provided a map (above) that shows the plane's possible location along one of two red semi-circles, based on a "ping" from a satellite orbiting 35,800 kilometers above the Indian Ocean. As you can see, this final data point indicates two possible flight paths: one northwest stretching toward Kazakhstan and another southwest into the Indian Ocean.

The northern flight path is above land, which would raise the odds that officials find the plane or its remnants. But The New York Times points out that it's unlikely that air-defense networks in India, Pakistan, or Afghanistan failed to pick up on a rogue 777. This makes the southern path more likely.
