(CNN) – It's not just planes, ships, and high tech underwater gear that could be critical in solving the mystery of Flight 370.
The FBI hopes good, old-fashioned forensics will also help shed some light on what happened. Specifically, they're looking into a flight simulator found at one of the pilot's home to see what files, if any, he may have deleted.
At this point, there's nothing indicating the pilots were planning the plane's disappearance. But with few clues as to what happened to Malaysia Airlines Flight 370, sources say the FBI is throwing everything it has at figuring out what's on the copy of the hard drive containing information from the captain's home flight simulator, and both of the pilots' laptops.
