All 13 people aboard a chartered plane heading to a tourist region of Papua New Guinea were killed when the plane crashed while approaching the rugged terrain during foul weather, Australia's prime minister said Wednesday. Papua New Guinea officials informed Australia that no survivors were found in the wreckage, which was located in the mountainous Kokoda region earlier Wednesday, Prime Minister Kevin Rudd told Parliament. The plane, carrying 11 passengers and two crew, vanished Tuesday morning in bad weather on approach to an airport in the Kokoda region. Nine Australians, one Japanese and three Papua New Guineans were on board. Two of the Australians killed in the crash were a father and a daughter, Rudd was quoted as saying by The Associated Press. The twin-engine plane left the capital of Port Moresby en route to an airport near Kokoda Track, a mountainous 60-mile (100-kilometer) trail. The plane's crew radioed air traffic controllers as it was approaching the airstrip, but the aircraft never landed, said Allen Tyson, a spokesman for Airlines PNG.
