The young Australian pilot who vanished without a trace after a supposed UFO encounter
| Name | The Disappearance of Frederick Valentich |
| Occurred on | October 21, 1978 |
| Seen by | No onsite witness |
| Investigated by | Department of Transport |
Nearly 50 years after the disappearance of Frederick Valentich, the mystery of what happened remains a topic of discussion in Australia, to the point where it has become part of the country’s folklore.
And who could blame them? With all the theories that have surfaced—from staged disappearance to UFO involvement—none could concretely explain and provide sufficient evidence on it.
To understand the story, let’s go back to that fateful night of October 21, 1978.
What Is the Disappearance of Frederick Valentich About?
Frederick Valentich was a 20-year-old pilot who had 150 logged hours of flight experience and a Class Four instrument rating license. The license permitted him to fly only on visual meteorological conditions (VMC).
The weather on the night of October 21 was clear, so he was good to fly over the Bass Strait to King Island in a single-engine Cessna 182L VH-DSJ. His departure time from Moorabbin Airport was at 6:19 PM, and he was expected to arrive at King Island Airport at 7:28 PM.
By all accounts, this should’ve been an easy flight—clear skies, aircraft in good condition, and the pilot had flown from Moorabbin Airport to King Island and back in the past, though this had been his first time doing so at night.
However, ~45 minutes into the flight, just minutes after he had finished telling Melbourne Flight Service Unit (FSU) officer Steve Robey that he had arrived at Cape Otway and was now beginning to cross the sea to reach King Island, he radioed Robey again. And this transmission was the last Robey, and everyone who had known him, had heard of Valentich again.
Here’s the abridged version of the transcript that recorded Valentich’s final moments:
At 7:06 PM, Valentich reported a large aircraft 5,000 feet below him and asked whether there was any known traffic in the vicinity. Robey replied none.
Valentich continued to tell Robey that the unknown aircraft was hovering around him, and that he couldn’t identify what kind of aircraft it was due to the speed it was travelling, as if it was playing some sort of game with him.
The aircraft in question was described as having a long shape, four bright lights similar to landing lights, a green light, and a metallic sheen.
At 7:11 PM, Valentich reported that his engine was running roughly and coughing. Robey asked about his intentions, to which he replied that he intended to go to King Island.
Then, at 7:12 PM, Valentich said his last words:
Melbourne, that strange aircraft is hovering on top of me again. It is hovering, and it’s not an aircraft.
What followed was roughly 17 seconds of metallic scraping noise. People who have heard the original recording said that this noise was “chilling” to hear. And we’re left to guess what Valentich was experiencing during those 17 seconds before the transmission completely cut off.
How Was the Disappearance of Frederick Valentich Investigated?
Before we proceed…
Because the investigation had considered the UFO angle, it’s best that we explain the roles of the agencies involved in the search for Frederick Valentich and the Cessna 182L VH-DSJ.
- DoT was responsible for the search action.
- DoT’s Air Safety Investigation Branch would investigate the circumstances that led to the disappearance.
- RAAF was to investigate UFO reports that were highly relevant to the disappearance.
The DoT only liaised with the RAAF because the newspaper reports and media interviews indicated the possibility of UFO involvement.
When Valentich failed to arrive at King Island Airport, the alarm was raised from the Alert Phase (which started at 7:11 PM when Valentich reported having engine problems) to the Distress Phase at 7:33 PM.
The DoT’s Actions
Immediately, the Department of Transport (DoT) mobilized personnel to conduct extensive air, sea, and ground searches between Cape Otway and King Island and the surrounding areas.
During the four-day search, which ended on October 25, the search party had found no significant leads to the whereabouts of Valentich’s body or of the Cessna 182L VH-DSJ. Even the oil slick that a search plane spotted on October 23 turned out to be a “tar discharged by a freighter or some other sea-going vessel,” as identified by the Department of Defence’s Materials Research Laboratories.
The RAAF’s Actions
On the Royal Australian Air Force’s (RAAF) side, they received and investigated 11 UFO sightings reported from October 18–21. Three of these reports came from professional pilots.
However, of the 11, only the one from 59-year-old bank executive Colin Morgan and his wife, Isabel, accurately matched with Valentich’s: a tube without wings, metallic and bright, and a green light.
It was low and traveling at unbelievable speed, cylinder shape, no wings, rows of windows, and a greenish plume. Yes, it looked like a four-pointed star with green vapor streaming from one of its points.
The ASI Branch’s Actions
As the DoT and RAAF conducted their side of the investigation, the Air Safety Investigation Branch interviewed Valentich’s family, girlfriend, friends, and people whom he met last, which included the crew at Moorabbin Airport.
They wanted to understand the incident—if Valentich’s aircraft might have malfunctioned, if he had personal issues to stage a disappearance, and other relevant motives or causes.
According to the compiled report (which many of the theories listed later are based on), it was found that:

What Was the Truth Behind the Disappearance of Frederick Valentich?
Despite the thorough investigation, the DoT couldn’t grasp concrete evidence to explain the disappearance of Frederick Valentich. Left with no choice, it could only declare this in the Aircraft Accident Investigation Summary Report:
The reason for the disappearance of the aircraft has not been determined.
The lack of evidence also gave birth, as mentioned earlier, to multiple theories. Here are some of them:
Staged Disappearance or Suicide
People close to Valentich didn’t believe that he’d deliberately vanish off the face of the Earth to commit suicide or go incognito. To them, he was a calm, cheerful, and intimate person who cherished familial ties.
However, theorists couldn’t write this possibility off for two reasons:
- His flunking the CPL exams and the possible prosecution he could face. It’s possible that he couldn’t accept the fact that he couldn’t prove to people, especially the RAAF, that he could become a full-fledged pilot.
- The fact that he didn’t request King Island Airport to turn on the aerodrome lighting meant it was possible that he might not have intended to arrive there at all. The reasons he told people for going there just support this.
Aircraft Crash
If Valentich did crash into the sea, theorists proposed two possible causes:
Victim of Optical Illusion
Of the theories, this one was the closest to reality—and one that skeptics also acknowledged. According to them, Valentich fell victim to the “illusion of a tilted horizon,” especially considering he wasn’t a capable pilot and had multiple flying incidents. Here’s how skeptics James McGaha and Joe Nickell explained it:
[Tilted horizon] can happen when the sun has gone down but still brightens part of the horizon, while, of course, the rest of it gets gradually darker farther away. This imbalance of lighting can cause the horizon to appear tilted, so that, in compensating by “leveling” the wings, the pilot inadvertently begins—not to orbit (circle), but to spiral downward—at first slowly, then with increasing acceleration.
At a most critical time, therefore, when he should have been in fully alert mode, paying attention to his instruments, he was instead engaged in something that was extremely distracting: flying while excitedly focusing on, and talking about, a UFO. This, as we can now see, was a recipe for disaster. With Valentich succumbing to spatial disorientation, his plane began what is aptly termed a “graveyard spiral.”
Hoax Gone Wrong
Brian Dunning found it peculiar that the transcripts were similar to a scene in Steven Spielberg’s Close Encounters of the Third Kind, which was released the year before the incident.
Because of this, it was theorized that Valentich was possibly trying to imitate the scene for fun. If successful, he could’ve cashed in on the fame and money. However, perhaps his fun had gone too far, which led him to crash.
UFO Abduction
The theories above were just that, theories. No concrete evidence was found to support them sufficiently.
This eventually led to the last and most widely discussed explanation: UFO abduction. Even Valentich’s own family believed he may have encountered a UFO and been taken, a theory often compared to other cases like the Emilcin Abduction. The idea continued to gain traction because:
- Valentich couldn’t identify the unidentified aircraft because it moved at incredible speed.
- No debris of the Cessna 182L VH-DSJ was found in the sea.
What Is the Significance of the Disappearance of Frederick Valentich in Ufology?
The disappearance of Frederick Valentich is a significant case that many UFO researchers still examine because:
- It gave us a recording of a possible UFO encounter in real time—and through an official aviation channel at that.
- It allowed us to realize how often pilots witness flying objects that didn’t match any of our known aircraft.
- It raised the question of how pilots should report possible UFO/UAPs while ensuring their safety.
- It showed how unprepared governments were to investigate UFO-related angles.
Today, the case is frequently cited in curated UFO reports and referenced in archived UFO documents that focus on pilot encounters.

FAQ
Has there been any progress in investigating Frederick Valentich’s disappearance since 1978?
There has been, but they have not provided any significant evidence to help solve the mystery of Valentich’s disappearance. For example:
- On May 15, 1983, a cowl flap was found on Flinders Island. However, the research lab could only state that it was from a Cessna 182 aircraft; they couldn’t definitively say whether it was the same Cessna that Valentich had piloted.
- On November 21, 1978, a pilot flying a Cessna 337 from Melbourne to King Island reported seeing plane wreckage in Bass Strait. But when he circled the area again, he couldn’t find it anymore.
Why was Frederick Valentich considered an incompetent pilot when he had 150 hours of flight experience and a Class Four instrument rating license?
Valentich was an incompetent pilot because of his poor exam results with the RAAF and his CPL, and because he was involved in flying incidents for which he received warnings or faced potential prosecution.
