WASHINGTON — Debris that washed up in Mozambique has been tentatively identified as a part from the same type of aircraft as the missing Malaysia Airlines Flight 370, a U.S. official said Wednesday. Photos of the debris that washed up over the weekend appear to show the fixed leading edge of the right-hand tail section of a Boeing 777, said the official, who spoke on condition of anonymity because he wasn't authorized to speak publicly. MH-370, which disappeared two years ago with 239 people aboard, is the only known missing 777. People who have handled the part, called a horizontal stabilizer, say it appears to be made of fiberglass composite on the outside, with aluminum honeycombing on the inside, the official said. The part is being transported to Malaysia. Mozambique's National Director of Civil Aviation Joao Abreu dismissed the report, saying authorities have found no part of the missing plane. But Malaysian transport minister Liow Tiong Lai tweeted to confirm the discovery.
