On 30 October1967, a driver reported a luminous object and an extraordinary interruption to his journey between Kojonup and Mayanup in Western Australia. The case became associated with Boyup Brook because that was where he went to the police. Its unusual feature is not simply an object in the sky, but his claim that a moving car stopped and resumed its former speed without any sensation of deceleration or acceleration.
The contemporary police record
The first page of Constable Leonard Johnson’s report, dated1November1967, identifies the reporting witness as Alexander Roy Spargo. It records that he attended Boyup Brook station at about9.35pm on30October and placed the sighting at approximately9.20pm. The road location is described through Kulikup and a distance from Mayanup, rather than a surveyed point.
The officer records Spargo driving alone in a1967Valiant utility with headlights on high beam. The car’s motor and headlights reportedly stopped, and the vehicle appeared stationary without the expected braking sensation. This is a record made shortly after the account reached police; it does not mean the officer independently witnessed the vehicle behaviour.
The published transcription of the complete report describes a light tube near the windscreen and an iridescent blue, football-like object above it. Spargo reportedly watched for around five minutes, heard nothing and felt as if he were being observed, although he saw no observer.
The account says the object disappeared in a flash and he then found himself travelling at his earlier speed, with the motor and lights operating. He subsequently stopped and inspected the vehicle without finding anything unusual. The report therefore preserves the driver’s experience of stopping; it contains no independent measurement showing how the car actually moved during the interval.
The later interview
Keith Basterfield’s 2012 review summarises interview material supplied by Dr Paul Zeck. The interview took place on2December1967 with the witness’s own doctor present. In that version the witness is called Mr Harris, a pseudonym; this does not represent a second person independently reporting the event.
The interview account expands the description of the hollow-looking light tube, the oval shape and the silence. It also includes a watch reportedly found five minutes slow after arrival at Boyup Brook. A discrepancy noticed afterwards may be part of the witness’s account, but it is not a separately monitored time record of the encounter.
Several dramatic features therefore come from successive versions of one person’s experience. Their repetition in a police transcription, an interview summary and later books should not be counted as three witnesses to an independently measured event.
Attempts to find corroboration
Basterfield’s original Boyup Brook Revisited article in UFO Research Australia Newsletter, July–August1983, pages3–6, traces the investigation more closely. The witness had heard that other people saw something on the same night. According to the published review, Zeck contacted the people concerned: two denied an unusual observation, while another account was interpreted as a satellite.
The article accordingly returns to a single principal witness. It considers several possibilities, including a dream or altered experience, a hoax and a genuine encounter. These are hypotheses discussed by the investigator, not established medical findings or demonstrated explanations. The article leaves judgement open rather than announcing a verified mechanism.
That distinction is essential. A detailed interview can establish what someone reported and test parts of the surrounding story. It cannot, merely through detail or the interviewer’s professional status, provide an independent record of a light beam or a vehicle’s motion.
How the date and description changed
Mark Rodeghier’s 1981 vehicle-interference catalogue, printed page38/PDF page48, dates the case31October1967 and describes a mushroom-shaped object. It cites Flying Saucer Review as its source. That entry is useful evidence of how the case circulated, while Johnson’s dated report supports30October and the football-like description in the police account.
The catalogue later uses Boyup Brook within its analysis of reported light beams and vehicle control. Inclusion in a statistical category does not establish that the individual report’s mechanism was verified. The classification follows what the witness was said to have experienced.
In the 2017 update accompanying the recovered police report, Basterfield notes a further difference: the police account gives an estimated30feet for the object’s diameter, whereas the interview document gives100feet. He also says he had not located a RAAF interview or a later signed police report requested through NICAP. These are documented limitations of his search, not proof that no other record can exist.
Outcome and the limits of the archive
UKPX classifies the case as Insufficient evidence. There is a contemporary police report and a substantial later source trail, but the central mechanical claim remains unmeasured and independently unconfirmed. The investigated corroboration did not produce another established witness to the same encounter. No unique cause is demonstrated in the reviewed sources.
The first police page has been inspected as a published image; the remainder has been read through its attributed transcription. The newsletter and catalogue were read in public PDF copies. The private interview tape and complete original interview file have not been obtained, and no personal records or private correspondence have been accessed.
Year, appearance tag and approximate location
The year filter records1967. The flashes filter follows the explicit departure description in the police transcription. Oval or football-like does not establish a sphere, disc or cigar, and feeling observed does not establish occupants or non-human contact. Neither electrical interruption nor a ground-level impression is automatically a landing or radar record.
The map gives an approximate Mayanup-area reference at33.93°S,116.45°E, rounded from the checked locality record. Source distances differ, so the point does not reconstruct the car’s stopping place. Calistemon’s2022 photograph shows Boyup Brook as the reporting town, rather than the encounter road or an evidential object.
