A sleeping plan took a turn for the worse when the pilot and co-pilot of an Airbus A330 aeroplane both fell asleep while the aircraft was in mid-air.
According to the UK Civil Aviation Authority (CAA), the event dates back to August 13, although the airline responsible has not been mentioned.
The incident happened shortly after the plane, which was boarded by 325 passengers, took off.
The pilots allegedly slept for less than five hours the previous night, so to ensure that one of them would always be checking the autopilot, they arranged a sleeping schedule.
However, they found that their plan was flawed when one of them woke up to find the other sleeping as well.
The pilots decided to report the occurrence to the aviation authority, which, despite making the case public, decided not to mention the airline responsible.
A CAA spokesman said: “This was a serious incident but an isolated one. I think lessons will be learned from this.”
