The Last Words Over Bass Strait

It is a Saturday evening in October, 1978. Spring in southern Australia. At Moorabbin Airport, on the edge of Melbourne, a twenty-year-old pilot named Frederick Valentich is getting ready to fly. He has hired a Cessna 182L. Its registration is VH-DSJ. His destination is King Island, a small speck of land in Bass Strait. The trip is one hundred and twenty-five nautical miles across open water. The story goes that he got his weather briefing, climbed in, and took off a little after half past six. The plane had been fuelled to capacity. That is about five hours in the air, for a flight of a fraction of that. Out over the coast, he calls in. At 1900 hours he tells Melbourne Flight Service that he has Cape Otway in sight. The weather there is clear. Excellent visibility. Light winds. A calm evening, a sound plane, a young pilot on a short hop. Then, at six minutes past seven, the call changes. Valentich tells Melbourne that an unidentified aircraft is following him. It is at four thousand five hundred feet. The controller checks and says there is no known traffic at that level. Valentich keeps talking. He describes a large craft, lit by four bright landing lights. It has just passed about a thousand feet above him, at high speed. Witnesses to the recording, and everyone who has since read the transcript, describe the same thing next. His voice stays steady, but the details keep coming. The craft came from the east, he says. He wonders whether the other pilot is toying with him. Now it is orbiting above him. It has a shiny metal surface, and a green light. Then his engine begins to run roughly. The controller asks him to identify the aircraft. And Valentich gives the line that will carry this story for decades. "It's not an aircraft." The transmission goes on. His last words, as the memorial at Cape Otway records them, are that the strange craft is hovering on top of him again. Hovering, and not an aircraft. Then comes a sound. The controller describes it as metallic, and scraping. And at twelve minutes past seven, the transmission is cut off. Melbourne calls him. Nothing. An extensive search begins, by land and by sea. Boats. Aircraft. The long grey water of Bass Strait. They find nothing. No wreckage. No oil slick that anyone can tie to the plane. No pilot. Not one trace of the aircraft or of Frederick Valentich, ever. And the story grows to fill that emptiness. People talk about lights in the sky that night. A farmer, some say, saw the Cessna stuck to a large UFO the day after. A photograph is said to show a strange object taken moments before the disappearance. There are theories about secret facilities. There are theories about abduction. There are those who point to the metallic scraping and say that is what alien technology sounds like. So here is where it stands. A calm, clear evening. A fully fuelled plane. A pilot describing, in real time, something he insists is not an aircraft. Then silence, and an empty sea. What was above him? And where did he go? Let's go to the record. The Australian Department of Transport investigated. It could not determine the cause. It declared the disappearance "presumed fatal." That is all. The official record never says UFO. And it never says anything else either. That is the first thing to hold onto. The search found nothing, so there was nothing for investigators to examine. The transcript points one way. The official conclusion points nowhere. Officials were sceptical that a UFO was involved. Some speculated that Valentich became disorientated. A pilot over dark water can lose the horizon. Out there, at dusk, his own lights reflected in the water, or the lights of a nearby island, might look like another craft. Some suggested he may even have been flying upside down. Spatial disorientation is the standard conventional explanation. But notice what it is. It was speculation by officials. It was not a finding. The investigation itself reached no cause. And it has a hard time with the details he gave. A large craft. Four landing lights. A pass a thousand feet overhead at high speed, and then an orbit. Those are specific claims. Sceptics add another point. Valentich had an interest in UFOs before that flight. That bears on how a pilot might read ambiguous lights, in a way the legend leaves out. What about other witnesses? Reports of a UFO sighting elsewhere in Australia that night did surface. But they were belated. They came after the disappearance was public, not at the time. Reports that surface after the news breaks are hard to weigh, because no one can say what those witnesses would have described without it. What survives from the night itself is the radio exchange. A transcript of it was later made public, and it is the backbone of every retelling. What it can't tell you is what Valentich actually saw. Then, five years later, the sea gave something back. An engine cowl flap washed ashore on Flinders Island. It was identified as coming from a Cessna 182, within a range of serial numbers. In July 1983, the Bureau of Air Safety Investigation asked the Royal Australian Navy Research Laboratory whether it could have drifted from the disappearance area. I can't tell you the answer. The outcome of that assessment isn't in what I have. So I can't say whether that piece of metal ever linked to Frederick Valentich. And that is the shape of it. No wreckage. No body. A disorientation theory that is only a theory. A cowl flap with no verdict. And a sound at twelve minutes past seven, metallic and scraping, that no account here explains. Believers read it as alien. Nobody offers a conventional reading. What was above him? A real craft, or a misread light? The record can't say. It only knows that a young pilot spoke into a microphone, and the sea went quiet.
