On 19 October 2009, a Boeing 767-300 being operated by Delta Airlines on a scheduled passenger flight from Rio de Janeiro to Atlanta inadvertently made a landing at destination in night VMC on parallel taxiway ‘M’ instead of the intended and ATC-cleared landing runway 27R. None of the 194 occupants were injured and there was no damage to the aircraft or conflict with other traffic or vehicles. The third rostered crew member had become incapacitated en route with the consequence that neither of the other pilots had been able to take any in flight rest.
