There are new details this morning in the investigation into the fate of Malaysia Airlines Flight 370. A Malaysian official said this morning that files were recently deleted from the flight simulator at the home of one of the pilots, Zaharie Ahmad Shah.

Investigators are trying to retrieve the files, as a massive search is underway in the southern Indian Ocean. If they can recover them, investigators would be looking for any practiced approaches into unusual destinations. There were reportedly five Indian Ocean runways found on the simulator.

On The Kelly File last night, we learned that co-pilot Fariq Abdul Hamid signed off for the night at least 12 minutes after the Boeing 777 started to head off of its designated flight path.

Hishammuddin Hussein told a news conference Wednesday that investigators are trying to retrieve the files. He also said that the pilot, Capt. Zaharie Ahmad Shah, is innocent until proven guilty of any wrongdoing.  

Hishammuddin said background checks have been received from overseas agencies for all foreign passengers on the plane except for those from Ukraine and Russia -- which accounted for three passengers. He says none of the checks has turned up anything suspicious.

Search crews from 26 countries including Thailand are looking for the plane that vanished March 8 with 239 people aboard en route from Kuala Lumpur to Beijing. Investigators have identified two giant corridors of territory spanning possible positions based on the flight's last faint signal to a satellite.

Aircraft from Australia, the U.S. and New Zealand on Wednesday scoured a search area for the missing Malaysian airliner stretching across 117,000 square miles of the southern Indian Ocean, about 1,600 miles southwest of Perth, on Australia's west coast.

A source close to the investigation told Reuters that investigators believe the jetliner is likely in the region. "The working assumption is that it went south, and furthermore that it went to the southern end of that corridor," said the source, who spoke on condition of anonymity.

The theory is based on the lack of evidence from countries along the northern corridor that the jetliner crossed their airspace, and the failure to find any trace of wreckage in searches in the upper part of one of two search corridors, Reuters reported.
