Malaysian officials on Saturday released this map showing two corridors that the missing Malaysia Airlines Flight MH370 might be located on.
The plane’s whereabouts remain unknown one week after it disappeared from civilian radar shortly after takeoff from Kuala Lumpur.
Malaysian Prime Minister Najib Razak said Saturday that, based on newly analyzed satellite data, the plane could have made last made contact anywhere along one of two corridors: one stretching from northern Thailand toward the Kazakhstan-Turkmenistan border, the other, more southern one stretching from Indonesia to the remote Indian Ocean.
Although U.S. officials previously said they believed the plane could have remained in the air for several extra hours, Najib said Saturday that the flight was still communicating with satellites until 8:11 a.m. — 7 ½ hours after takeoff, and more than 90 minutes after it was due in Beijing. There was no further communication with the plane after that time, Najib said. If the plane was still in the air, it would have been nearing its fuel limit.
A U.S. official with knowledge of the investigation on Friday said the only thing the satellite can tell is how much it would need to adjust its antenna to get the strongest signal from the plane. It cannot provide the plane’s exact position or which direction it flew, just how far the plane is, roughly, from the last good data-transmission location when the digital datalink system was actually sending data up to the satellite.
The U.S. official said the search area is somewhere along the arc or circumference of a circle with a diameter of thousands of miles.
The new leads about the plane’s path, though ambiguous, have drastically changed a search operation involving more than a dozen nations. Malaysia on Saturday said that efforts would be terminated in the Gulf of Thailand and the South China Sea, the spot where the plane first disappeared from civilian radar.
Malaysian authorities are now likely to look for help from other countries in Southeast and South Asia, seeking mysterious or unidentified readings that their radar systems might have picked up.
Correction: An earlier version said the satellite data indicated possible flight paths of the missing plane.
