In theory, at least, airlines will soon have a wider choice of planes. On November 2nd COMAC, a Chinese state-owned aircraft manufacturer, revealed its C919 plane (pictured), a competitor to Airbus’s A320 and Boeing’s 737, the two most popular planes in the skies. COMAC says the C919 will have its maiden flight next year—two years later than first scheduled—and will enter service around 2019. The Chinese are not the only ones who think they can break the duopoly. After several delays, Irkut, part of Russia’s state-owned United Aircraft Corporation (UAC), hopes to launch its MC-21 aircraft, another potential rival to the 737 and A320, into service in 2017.
