Malaysian police have searched the homes of both the pilot and the co-pilot for clues to the whereabouts of flight 370. Some experts are critical of the investigation, saying the move is long overdue.
"For them to wait this long to look into the pilots' homes is really inexcusable," said Mary Schiavo, Former Inspector General, U.S. DOT.
Plane disappearance "deliberate"? The searches were prompted by analysis of electronic and satellite data that shows the plane was flying a strange path.
"These movements are consistent with deliberate action by someone on the plane," said Najib Razak, Malaysian Prime Minister.
The movements led investigators to broaden the search area. They believe after communication was cut off, the plane turned and flew west over the Malaysian peninsula, and then went either northwest, toward the bay of Bengal or southwest, over the Indian Ocean.
"The aviation authorities of Malaysia and their international counterparts have determined that the plane's last communication with a satellite was in one of two possible corridors," said Razak.
The northern corridor stretches from the border of Kazakhstan and Turkmenistan all the way over to northern Thailand.
The southern corridor stretches from Indonesia into the southern Indian Ocean.
With the focus now on the area west of Malaysia, searches of the South China Sea are being abandoned.
Despite these renewed efforts, experts continue to criticize the investigation.
"How do you make heads and tails of any of this?" said Michael Schmidt, New York Times.
"The Malaysian authorities are making no sense at this point, so I question whether they believe their theories. I think they're just grabbing at straws," said Schiavo.
The search now includes 43 ships and 58 aircraft from 14 different countries. The foreign embassies of all the countries included in the new search area have been given access to the Malaysian authorities' information.
