Air New Zealand said Friday that one of its pilots fell into a deep sleep while at the controls of an international flight but insisted that safety aboard the aircraft was never compromised.
He was one of two pilots flying a 332-seat Boeing 777-300ER from London to Los Angeles in November 2011, according to a report released after a freedom of information request.
The Civil Aviation Authority (CAA) document said the pilot voluntarily submitted a "fatigue report" with the regulator, recounting how he slept on the job.
The pilot, who was not identified, blamed a poor night's rest in London, when air-conditioning problems in his hotel meant he had to change rooms three times, for his exhausted state on the flight.
