The NTSB will now work to find out what caused the crash. Johnson said investigators have plenty of clues.
"The flight data recorder, the cockpit voice recorder, lots and lots of data in addition to the physical evidence," he said. "The airplane itself as far as crush zones, damage to the airplane, all that is going to be studied."
