Sierra Kilo Charlie was the call sign for a chartered Beechcraft 200 Super King Air which crashed near Mount Isa, Queensland, Australia on Monday 4 September 2000, killing all 8 occupants. The flight plan for the aircraft called for the pilot to fly between Perth, Western Australia, and the mining town of Leonora, Western Australia. During the flight, the aircraft climbed above its assigned altitude. When air traffic control (ATC) contacted the pilot, the pilot`s speech had become significantly impaired and he was unable to respond to instructions. Three aircraft intercepted the Beechcraft but were unable to make radio contact. The aircraft continued flying on a straight heading for five hours before running out of fuel and crashing near Mount Isa. The incident became known in the media as the "Ghost Flight".
