One of the most controversial radar visual reports of the 1950's occurred on August 31st, 1954. The story leaked out in December, 1954, and made front page headlines. The official navy file on the event remained classified until the Directorate of Naval Intelligence released a copy upon request in 1982.
Lt O'Farrell was flying a Sea Fury aircraft, and noticed a very bright light closing fast from the 1 o'clock position. The light crossed ahead of him, and continued to a position on his port beam where it appeared to orbit. At the same time he noticed a 2nd, similar light at 9 o'clock, which made a pass ahead of him and then turned in the position where the first light had been sighted. The pilot contacted Nowra radar who confirmed they had 3 echoes on screen. The two bright lights reformed at 9 o'clock and disappeared on a north-easterly heading.
