Aviation experts puzzled after airliner dumps fuel over citySome aviation experts said Wednesday that they were puzzled after the crew of a commercial airliner decided to dump fuel at low altitude during an emergency landing, causing a vapor to fall on schoolyards and neighborhoods east of Los Angeles International Airport. Delta Air Lines said Flight 89 to Shanghai had an engine problem after takeoff Tuesday and needed to quickly return. The Boeing 777-200 landed safely after circling back over Los Angeles while dumping fuel to reach a safe landing weight, the airline said in a statement.
