Malaysia Airlines Flight 370: New Data Shows Focus in the Southern Indian Ocean

March 25, 2014— -- The search for Malaysia Airlines Flight MH370 remains focused in the southern Indian Ocean -- where Malaysian investigators repeated today is the area where the plane crashed -- since new data shows it remains the jetliner's last-known position, officials said.

In a news briefing this morning, Malaysian officials said detailed satellite data from the British firm Inmarsat and a new timeline showed the plane flew south in the Indian Ocean off the coast of Perth, Australia and that the search zone has now been reduced roughly to the size of Alaska.

Malaysia's Acting Transportation Minister Hishammuddin Hussein said "this type of analysis has never been done in an investigation of this sort" and that the search in the northern corridor had been called off as a result.

"We are currently working to further narrow down the search area, using the four methods I mentioned ... gathering information from satellite surveillance, analysis of surveillance radar data, increasing air and surface assets and increasing the number of technical and subject matter experts," he said.

Malaysian officials believe the plane vanished somewhere over water since the jetliner had little fuel remaining and no nearby landmass in which to make an emergency landing. The focus, officials said, is recovering the plane's black box.

Investigators are still trying to determine what happened to the plane after it took off around midnight from Kuala Lumpur, Malaysia, headed for Beijing, China. It disappeared off the radar shortly after 1 a.m. but continued to fly, according to satellite data, for up to seven hours.

The search operation, suspended today because of bad weather in the Indian Ocean, is focused on an area that includes 469,407 square nautical miles -- roughly the size of Alaska -- and that officials are attempting again to "narrow down the search area," said Hussein.

Last week, officials had announced that they were looking for the Boeing 777 in a search area of 2.24 million square nautical miles.

Malaysian officials, in a detailed news release, explained that the new analysis has helped in the recreation of a new timeline and confirming the direction in which the plane flew along the southern arc before disappearing.

"As the search area has narrowed, new challenges have arisen, including managing resources in a remote search and rescue effort," the statement from Malaysian officials read. "We continue to work closely with our friends and partners as we seek to marshal more specific resources in support of the operations in that area."

The statement continued, "No response was received from the aircraft ... when the ground earth station sent the next log on/log off message. This indicates that the aircraft was no longer logged on to the network. Therefore ... the aircraft was no longer able to communicate with the ground station. This is consistent with the maximum endurance of the aircraft. This analysis by Inmarsat forms the basis for further study to attempt to determine the final position of the aircraft. Accordingly, the Malaysian investigation has set up an international working group, comprising agencies with expertise in satellite communications and aircraft performance, to take this work forward."

The multinational search, which includes 26 countries, now enters its third week after the Beijing-bound plane vanished March 8 with 239 people on board.

"If there is hope -- even against hope -- we will do whatever it takes," Hussein said when asked about finding the plane.
