The FBI is working to recover deleted files from the Malaysia Airlines Flight 370 pilot's flight simulator's hard drive.
Investigators hope the erased files will provide some insight into the pilot's mindset before the flight went missing.
Could the pilot have used his homemade simulator to practice flying in unfamiliar territory? Or perhaps landing on a short runway?
CNN's Martin Savidge is in a Boeing 777 simulator with pilot trainer Mitchell Casado to demonstrate landing on a short runway.
