China's comac to challenge Boeing and Airbus

The C919, China's answer to the Airbus A320 and Boeing 737, is slated to have its first test flight later this year. Built by the Commercial Aircraft Corporation of China (Comac), the twin-engine airliner had its celebratory rollout last November in Shanghai. But even if this year's flight-testing goes well, don't expect to fly on a C919 right away. Indeed, if you live in Europe or the United States, don't expect to even see one at your local airport.
