Saint-Denis, Reunion Island (CNN) Boeing investigators are confident that debris found on a remote island in the Indian Ocean comes from a 777 aircraft, according to a source close to the investigation.
An international team of aviation experts is trying to determine if that airplane part comes from Malaysia Airlines flight 370, a Boeing 777 that disappeared in March 2014 with 239 people on board.
A match might help solve the mystery of what happened to that airplane, since no other 777s in the world are unaccounted for, according to the Aviation Safety Network, an online database of flight incidents.
