BALMA, France — A wing flap suspected to be from the missing Malaysia Airlines Flight 370 on Saturday arrived at a French military testing facility where it will be analyzed by experts. After a 10-hour journey by road from Paris’ Orly airport, a truck carrying the roughly 8-foot component known as a flaperon arrived at the DGA TA aeronautical testing site near Toulouse, accompanied by police motorcycles and a police car. French aviation experts will try to establish whether the wreckage that was found on the Indian Ocean island Reunion comes from Flight 370 — a Boeing 777 which disappeared on March 8, 2014, while en route from Kuala Lumpur to Beijing with 239 people on board.
