MH370: Korang Tengok Di Mana Peliknya?

Military radar detection: 2:15 a.m.

Though the Malaysian plane is not transmitting information -- by ACARS or transponder -- radar on the ground or elsewhere can still detect a plane in the air.

According to a Malaysian Air Force official, military radar tracked the plane as it passed over the small island of Pulau Perak in the Strait of Malacca.

At this point, the plane was now hundreds of miles off-course. In fact, it was on the other side of the Malaysian Peninsula.

Military radar showed that the jetliner flew in a westerly direction back over the Malaysian peninsula, Malaysian Prime Minister Najib Razak said. It is then believed to have either turned northwest toward the Bay of Bengal or southwest elsewhere into the Indian Ocean.

This was the last time any civilian or military radar tracked the aircraft.

The focus now is searching for the missing flight in the southern Indian Ocean, according to a U.S. official.

"The southern scenario seems more plausible," the official said.

The Malaysian military is now handing over its raw radar data to U.S. and UK officials, apparently setting aside concerns about any sensitive military intelligence.

Quest called this sharing of information a "huge" development in the case.

"They don't want anyone to know how good their radar is. They obviously decided that doesn't matter," he said.

"We don't know much about the Malaysian military, and that has been one of the issues," Quest added. "It appears that Malaysia was providing an interpretation of the analysis -- and not the raw data. Now they are handing over the raw data."

Satellite 'handshakes': 8:11 a.m.

Prime Minister Najib revealed Saturday that a satellite tracked the plane at 8:11 a.m., more than seven hours after takeoff.

Najib didn't provide details on the satellite tracking, but it appears that orbiters high above the ocean detected the plane as the satellite or satellites attempted a series of "handshakes" -- or electronic connections -- with the plane below, Quest said.

It's likely that the plane didn't complete the handshake because its communication systems were disabled, Quest said. It's also possible that the airline doesn't subscribe to that part of the satellite system, he said.

Nevertheless, the satellites would have been able to trace a plane flying below them and would have extended an electronic message equivalent to a hailing: "There's a plane: Hello, hello, hello? Do you have anything for us?" Quest said.

The Prime Minister said the "raw satellite data" confirm that the plane was Malaysia Airlines Flight 370. The U.S. National Transportation Safety Board and the Federal Aviation Administration, along with the UK's Air Accidents Investigation Branch, concur, Najib said.

"Due to the type of satellite data, we are unable to confirm the precise location of the plane when it last made contact with the satellite," Najib said.

Authorities believe the plane was in one of two flight "corridors": a northern route stretching to northern Thailand, Kazakhstan and Turkmenistan and a southern route toward Indonesia and the southern Indian Ocean.

More than a week after its takeoff, however, the whereabouts of the plane remain a mystery.
