Highest civilian airport opens
China has begun flight operations at the world's highest civilian airport in a bid to boost tourism.
At an elevation of 4,411 metres (14,472 feet) above sea level, Daocheng Yading Airport replaces the previous champion, Bangda Airport in Tibet, which sits at 4,334 metres (14,219 feet).
Aircraft engines produce less thrust at such elevations because of the much thinner air, calling for longer runways.
State media say flights from the new airport that began on Monday will slash travel time from scenic Daocheng Yading to Sichuan's provincial capital of Chengdu from two days by bus to just 65 minutes.
