From takeoff to final satellite signal - a timeline of Malaysia Airlines Flight 370

It all began early Saturday morning - March 8.

Sometime after Malaysia Airlines Flight 370 took off at 12:41 a.m., investigators believe someone re-programmed the plane's flight management system to turn away from its original flight plan. Then 26 minutes after take-off, the plane sent its last automatic maintenance data transmission to the airline.

At 1:19 a.m., the co-pilot, Fariq Hamid, told air traffic controllers in Malaysia, "All right, good night," as the plane moved toward Vietnamese airspace. They were the last words heard from the cockpit.

Two minutes later, at 35,000 feet, the transponder was turned off. The plane went dark on civilian radar, and then made a left turn back toward Malaysia.

Sources say it followed an established aviation corridor over several navigational "waypoints."

The Malaysian military tracked an unidentified object on its radar traveling west towards the Strait of Malacca. Authorities now believe that was Flight 370. At 2:15 a.m., it disappeared from the military radar, about 200 miles northwest of Penang.

Investigators also say the plane's antenna signaled to a satellite multiple times over the next several hours. The last signal came at 8:11 a.m., about the time the plane would have run out of fuel.

That last satellite contact led authorities to dramatically expand the search area. Now there is a lot of focus on the south Indian Ocean. The National Transportation Safety Board is now helping Australian authorities pinpoint locations to search.
