On 14 January 1962 James Knight commenced a flight from Ceduna, South Australia to Cook, South Australia (c.220 miles WNW) in Wackett VH-BEC (ex-RAAF A3-139). He was never seen again. Over three years later, on 28 March 1965, VH-BEC was found by chance two hundred miles north of Cook. Knight had remained with the aircraft after it force-landed and inscribed a diary and his Last Will and Testament on the fuselage panels; the last diary entry was made on 20 January 1962. It was subsequently determined that the mount of the magnetic compass was loose and displayed headings that were 30 degrees in error. VH-BEC was recovered in 1977 and is now on display at the Central Australian Aviation Museum at Alice Springs.
