A Boeing 747-400 made an emergency landing at Phnom Penh International Airport airport on Tuesday, showing the airport's enhanced capacity to handle large aircraft and to respond to emergencies, said the airport authority in a statement. The cargo aircraft was operated by Cargolux Airline and was travelling from Syria to Ho Chi Minh City when it was rerouted to Phnom Penh due to congestion at the Vietnamese airport. The statement added that it is building new runways to accommodate 747s on a regular basis.
