Sleeping Chinese air traffic controllers leave plane in limbo

China Eastern Airlines flight was preparing to land at Wuhan airport when 12-minute air silence forced it to delay approach

A Chinese aircraft was forced to delay its landing after two air traffic controllers nodded off, reports said on Tuesday, sparking a wave of online anger about airline safety.

The Boeing 737 was preparing to land at Wuhan airport in central Chinabut had no response from the air traffic control tower for 12 minutes, reports said.

Contact was eventually made and China Eastern Airlines flight MU2528 from Sanya landed safely, according to Sina.com.

"Because air traffic control was asleep on duty, [the plane] called many times," civil aviation authorities said in a statement quoted by the Chinese business magazine Caijing.

"But there was no reply, and no contact could be made with the control tower."

A separate investigation report cited by Caijing said two controllers had fallen asleep.

The incident happened on 8 July and the statement was dated 29 July. There was no explanation for the delay in making it public.

"Air control work is truly exhausting, but it is unforgivable to sleep on duty," a post on Sina Weibo, China's version of Twitter, said Tuesday.

"Hundreds of people's lives depend on the actions of flight tower controllers. We entrust our lives to you," the post continued.
