Malaysian and Australian officials have confirmed that a piece of an aircraft wing found in Mauritius has been identified as belonging to missing Malaysia Airlines Flight 370. The piece of wing flap was found in May and subsequently analysed by experts at the Australian Transport Safety Bureau. Investigators used a part number found on the debris to link it to the missing Boeing 777. Several pieces of wreckage from the plane have washed ashore on coastlines around the Indian Ocean since the aircraft vanished with 239 people on board during a flight from Kuala Lumpur to Beijing on March 8, 2014. So far, none of the debris has helped narrow down the precise location of the main underwater wreckage. Investigators need to find that in order to locate the flight data recorders that could help explain why the plane veered so far off-course.
