The FBI is looking at a flight simulator's hard drive taken from the home of Malaysia Airlines Flight 370 Captain Zaharie Ahmad Shah.
The agency is also looking at the pilot and co-pilot's computers, searching for any piece of information that may be key to the investigation.
As for the search for the plane, the United States and Australian search teams are focusing their efforts on the waters off Australia's west coast.
But could the plane have flown that far without being detected by radar?
