Lieutenant J. A. O'Farrell, known as Shamus, was flying a Sea Fury alone on a navigational patrol when two brilliant white objects came up on either side of him and held formation about thirty metres off each wing. He was at 13,000 feet. On the ground the radar operator Keith Jessup had all three on his scope. The Air Force and Sydney airport were asked and confirmed that no known aircraft were aloft in that airspace. The two objects then broke away and left at a speed the account estimates at more than a thousand knots.
What is on the record
One channel, one video, one telling. The archive resolves four claimants: O'Farrell himself, Jessup at the radar, an engineer at the Merulin radio tower and an air traffic controller at Sydney. Two of those are described as independent ground witnesses to the same event, which is what gives the case its shape. An aircrew report, a radar track and observers on the ground pointing at the same thing is a stronger combination than testimony alone.
What the archive does not hold is any of the paperwork. The account states that the file was classified for more than thirty years, and that is the source's claim. No released document sits in this entry to check it against, so the radar track exists here as a description of a radar track rather than as a record of one.
The sheet is imprecise about place. It names airspace near Nowra in southern New South Wales while its coordinates fall well inland of there, so the location should be taken from the name and not the pin.
Why it sits where it does
The case grades L3, independent testimony describing one connected event. Its evidence class is testimony rather than official record, because the file that would carry it is not in the archive. Were that file to surface, this is the kind of case that would move. What formed up on O'Farrell's wingtips is not resolved here.
