New information on Flight 370's course changes help narrow the search area

Investigators say part of the plane's diverted route was preprogrammed to hit two navigational waypoints. All this comes as the FBI examines hard drives from the captain's home flight simulator and tries to recover deleted files. Anderson lays out a timeline of the latest developments.
