A pilot for Japan?s All Nippon Airways fell asleep at the controls while on a domestic flight and had to be awakened by a government inspector traveling in the cockpit. But he dozed off again and had to be awakened a second time.

A spokesman for the airline said that the 50-year old pilot, dozed off while flying on March 23 from Tokyo?s Haneda airport to the western prefecture of Yamaguchi, a trip that takes about an hour.

The spokesman said there was no danger to passengers since the plane was on auto-pilot and the co-pilot was also present. The pilot, who has been suspended, is undergoing medical tests.

Last year, a Japanese bullet train driver fell asleep at the controls while his train was traveling at 270 km (168 miles) an hour. He was found to suffer from sleep apnea, in which a person repeatedly stops breathing during sleep, causing daytime drowsiness.
