A co-pilot that plunged a plane 120 metres over the Atlantic because he mistook the planet Venus for another aircraft has had the incident blamed on fatigue.
According a report by the Canadian authorities, the pilot had woken up from a 75-minute nap on the flight from Toronto to Zurich and was disorientated. The incident caused minor injuries to 16 people as they did not have their seatbelts on, so hit their heads on the ceiling during the 46-second dive. All injured passengers and crew were taken to hospital when the aircraft landed in Zurich.
The Canada Pilots Association has now called for a third pilot to be mandatory on overnight flights.
