Boeing 737-800
Airport officials say a Boeing 737-800 was found to have a missing panel after a United Airlines flight arrived at its destination in southern Oregon.
Sunday's discovery may shed light on why the Boeing 737-800, carrying 132 people, nosedived into a remote mountainous area last week.
Investigators found what they believed to be the cockpit voice recorder Wednesday.
The exterior of the black box recorder was so damaged that investigators could not immediately conclude whether it was the flight data recorder or the cockpit voice recorder.
