I have just obtained a copy of a previously unseen RAAF file from the National Archives of Australia. File series J229, control symbol 5/13/Air, barcode 21290309 has a date range of 1956-1966, and is titled 'Sighting of unidentified objects.' It originated from 10 (MR) Squadron RAAF, based at Townsville, Queensland, Australia. It is 130 pages in digital format.
Among reports of a probable meteor (Townsville 13 Oct 1956); probable lightning flashes (Townsville 20 Jul 1957); a probable submarine intruder (during exercise Tuckerbox II, 12 Sep 1962 at 1922S, 15450E); another probable submarine sighting ( 27 Sep 1963 in the Torres Strait), is a much more intriguing set of photographs.
On 16 May 1958, a Lincoln aircraft A73-60 photographed Cartier Island, at 0220Zulu, while flying at 1500 feet, using a 5 inch lens.
A memo from the Squadron photographic officer to the commanding officer, 10 Squadron, dated 29 May 1958, states in part:
|The location of the island|
'After normal processing film was numbered and assessed for printing during which time object was discovered.'
|Dimensions of the object|
|Close up of object|
This second flight was carried out on 3 August 1958. Part of the resultant report read 'A visual survey of Cartier Island was carried out at low level. Nothing could be seen in the area off the western end of the reef in the vicinity of the reported unidentified object.'
The object, remained unidentified.
