PP474/1 5/5/AIR — RAAF Western Area (Western Australia) UFO File

Brief

On 28 November 1957, witnesses at Eucla, Mundrabilla Station, and Madura simultaneously observed a cigar-shaped object roughly 30 feet long trailing blue smoke at 7,000-10,000 feet; a portion of the object detached and plummeted to earth, while a station hand 10 miles away heard an explosion and observed a mushroom-shaped cloud. A separate July 1957 event at the Fibre Queen Asbestos Mine near Marble Bar produced corroborating eyewitness accounts of a brilliant green light, sequential explosions, and a motor-like noise; WA Police triangulated a probable impact site in the Dalton Creek area. A 1956 civilian report from Wongan Hills described a pulsating red-and-green object that hovered, executed rapid circular maneuvers, and departed vertically — dismissed by RAAF headquarters as probable Jupiter refraction. DEPAIRCAN signals from April and June 1960 requesting sighting reports of anticipated atmosphere reentry close the file, confirming the same reporting channels handled both orbital-decay tracking and civilian UAP intake.

Key points

• Three simultaneous civilian witnesses at Eucla, Mundrabilla Station, and Madura independently described a cigar-shaped object approximately 30 feet long with a shiny nose cap, trailing blue smoke, at an estimated altitude of 7,000 to 10,000 feet on 28 November 1957.p.8
• A portion of the Nullarbor object detached and followed the main body for approximately 400 yards before plummeting to earth; the sole eyewitness was caring for a sick daughter and no search of the fall site was made.p.11
• Mundrabilla Station hand Jim Henderson, 10 miles north of the homestead, did not see the object but heard a loud explosion followed by a mushroom-shaped cloud that settled into smoke 'like a willy-willy' — corroboration from an independent location.p.8
• WA Police formally flagged the Nullarbor object as a potential hazard to the standard East-West transcontinental air route, elevating the report from curiosity to aviation-safety concern.p.8
• RAAF queried Air Task Group BUFFALO EDINBURGH — the unit supporting Operation Buffalo nuclear tests at Maralinga — and received a nil-activity response, formally ruling out that program as a source of the November 1957 sighting.p.26
• WA Police constable Ian Blair triangulated directional bearings from Pilga Station, Hillside Station, Marble Bar, and the Coongan Lead Mine to place the probable ground impact of the 3 July 1957 Marble Bar green light in the Dalton Creek or Soansville area between Pilga Station and the Fibre Queen Mine.p.16
• Mine manager Richard Webber and worker Ronald Walker gave independently consistent accounts of a brilliant green light, sequential explosions, and a subsequent noise resembling a misfiring motor truck that began when the light started moving and ceased when it disappeared — July 1957, Marble Bar.p.17
• Civilian D. Pike (Wongan Hills, 4 July 1956) described an object pulsating in clear alternating red and green with no white, capable of hovering, executing rapid circular evolutions, and departing vertically at high speed; RAAF attributed it to Jupiter refraction without field investigation.p.32
• DEPAIRCAN signals AI232 and AI235 (April and June 1960) requested RAAF units to report sightings of anticipated atmosphere reentry events, confirming the same Western Area channels handled orbital-decay monitoring and UAP intake simultaneously.p.5

Verbatim

• I came out of the house about 9 p.m. last night and at once noticed what I took to be a rather bright star low in the sky and that was changing colour like the evening star does.

Most interesting

• The Mundrabilla-Eucla corridor where the 1957 cigar-shaped object executed its looping flight path is the same stretch of the Nullarbor Plain as the 1988 Knowles family encounter, suggesting a recurring hotspot across three decades.
• Witnesses described the Nullarbor object approaching from a southwesterly, seaward direction before circling inland to Madura, returning to Mundrabilla Station, then re-crossing Eucla heading east toward Fowlers Bay — a sustained, directional flight path inconsistent with an unguided ballistic missile.
• The nil-activity response from Air Task Group Buffalo Edinburgh is significant: Operation Buffalo was the 1956 British nuclear test series at Maralinga, and its dedicated air support unit's formal denial eliminates nuclear-test activity as a candidate explanation for the November 1957 sighting.
• Police constable Blair identified a probable impact zone (Dalton Creek/Soansville) through multi-point triangulation of eyewitness bearings, yet no organized ground search was ever mounted.
• D. Pike's 1956 letter to Air Force Intelligence in Perth also reported an unexplained explosion 'just before 12 noon' on the preceding Monday that shook buildings across Wongan Hills — a corroborating acoustic event RAAF's Jupiter-refraction reply did not address.
• Ronald Walker's statement explicitly ruled out a meteor interpretation on acoustic grounds: witnesses 'did not think that it was a meteor because of the noise which seemed to accompany it' — the motor-like sound persisted after the light was gone.
• The RAAF's response to D. Pike was signed by a Squadron Leader acting for the Air Officer Commanding, indicating the file reached command level before being closed with a natural-phenomena explanation.
