Hessdalen — The noise that never arrives

His name is Nils Kåre Nesvold. He is driving a green Ford Cortina on a road near Nesvollen, in Norway. It is 20 December 1981. Before a railway crossing, below the ridge, he sees a light and stops. The first word that comes to him is ordinary: helicopter. So he gets out and listens. But the sound of rotor blades never arrives. The light, he will later say, looks oval, as bright as a light bulb. He cannot tell how far away it is.

Nils uses a walkie-talkie to call his friend Per Holden, gets back into the car and goes to pick him up. For now, all Per has is Nils's voice over the walkie-talkie.

Three months earlier, at the end of September 1981, in Støren, Olaf Hansen and his wife look out of a window at around eleven at night. They see a white-and-blue light moving slowly along the valley. To them it looks like an aircraft. They open the window to hear it pass. The roar never comes.

The open window stays with me. To check an aircraft, all they had to do was wait for its sound; the sound never comes.

The light seems low, broader at the front than at the back. Olaf also thinks of a car or a train, but that night he sees no traffic. He and his wife follow it with their eyes until a mountain hides it.

Back to the road. Nils returns to the railway crossing with Per. According to Nils, Per does not believe him at first. The Ford drives the same road again; then Per sees the light too. They continue towards Rugldalen, stop and get out. The light disappears.

A few hours later, Halvard Bakås is driving another road, from Ålen towards Hessdalskjølen. He too sees a light on the opposite slope and chooses an ordinary explanation: a snowmobile with its headlight on. Or a cabin. Later he is told that there were no snowmobiles or people in the cabins he had in mind; he adds that, from where he was standing, those cabins would not have been visible.

Before they call anything a mystery, they look for something familiar: the sound of rotor blades, a headlight, a cabin. They are different people, in different places and at different times. No one can tell us that they saw the same light.

One and a half years after the first winter of reports, on 3 June 1983, Project Hessdalen is formed. The valley is about twelve kilometres long and, according to the project report, has about one hundred and fifty inhabitants at the time. In January 1984 the group sets up a headquarters in a caravan at Aspåskjølen; other observers take positions on the hills and near Lake Hersjøen.

The difficulty is practical: when a light appears, do you watch it, or run to get the camera? The report preserves more than one occasion when time, hands and equipment were not enough to capture the whole event.

The campaign begins on 21 January 1984. The observers record a light moving irregularly, then drawing what they will describe as a large S before disappearing. They manage to photograph one phase of it; the curve remains in their account.

Four days later, on 25 January, Arne and Tone Thomassen see a light that at first looks like a planet. Then it moves. Arne photographs it and tries to obtain a spectrum. The film, however, is too weak to say what it was.

On 27 January, Jon Aspås and Ruth Marry Moe are looking through binoculars. An aircraft has just passed. Then they notice another light above Finnsåhøgda. To their eyes, it is moving quickly.

Let us stop before they can decide what they have seen. In the caravan, Leif Havik is watching a screen. Two echoes appear on the radar, one after the other. Leif goes outside, reaches Jon and Ruth and asks what they observed. The team will later write that the observations were only a few seconds apart and pointed in a compatible direction. It is a clue. It is not enough to say that the radar and the two witnesses were following the same light.

Six days later, on 2 February, Leif is at Jon Aspås's house for a coffee break. A phone call reports lights towards Finnsåhøgda. Leif goes out with a camera and a telephoto lens, without a tripod. In his account there are three lights: two bright ones and a red one at the front, with a dark area between them. Some people read them as a single object. They seem to sway.

Going back to the caravan for the equipment would take time. Leif takes the photographs from where he is; the headquarters is empty and its instruments do not record the event. After development, the images contain blurred streaks. The camera was handheld and shook. The film does not let us retrace the trajectory with confidence.

The witnesses call the lights “the object” because of the shape they seemed to draw. The dark area between them was not measured. The photograph cannot decide whether they were looking at one structure or several sources.

On 12 February, a flashing light moves slowly across the field of view from the main observation post. Erling Strand has a laser. Kurt Persson watches through binoculars. Erling points the beam towards the light; Kurt says that the flashing seems to split in two. The beam moves down and the rhythm becomes single again. It rises, and Kurt reports two flashes again. Later they repeat the procedure with a similar light, without Kurt seeing where Erling is pointing. May Britt Pellving is present. The report counts nine attempts; in eight, the observers record the change.

If I had been there, I think I would have said at once: “It answered.” That is the phrase that would have come naturally to me. The observers instead recorded the sequence of their gestures and the flashes. There is no continuous recording of the rhythm, and no test prepared in advance to rule out coincidences or observation errors. Something happened that was worth recording; the report still cannot say that the light reacted to the laser.

Five days later, on 17 February, Ove Joakim Karlsson and Dick Ekenhage climb towards an observation post near Lake Hersjøen. On the opposite slope there is a stationary yellow light. They film it and take a few photographs; after ten minutes, then twenty, it seems reasonable to call it a cabin window. They keep climbing.

Later they see a yellow point first, then two nearby lights that change direction and seem to draw closer. Joakim calls the caravan on the walkie-talkie. A few seconds later the lights go out. I find myself imagining the cabin light breaking loose and moving. The report does not say that this happened: it describes the stationary point and the later lights, but the film does not show that they were the same source.

Three days later, on 20 February, Leif Havik opens the caravan door. Åge Moe and Edvin Kværnes are waiting outside. At that moment, the report says, a red light appears on the ground and moves around his feet. It lasts a few seconds. Then it disappears.

Åge thinks it is a reflection. Leif connects the colour with the laser the team has used, but the instrument is not there at that moment. Five days later they bring it back to the caravan and point the beam at the snow. Åge says it looks very much like what he saw, with slightly different intensity. It is a comparison made afterwards, not a reproduction of the original light.

As soon as the red point disappears, the people present look up. The sky above the caravan is covered, except for a small opening between the clouds where the stars can be seen. The report also considers the houses in the area and says their position does not easily explain what was seen beside the door. That remains the authors' assessment, not a measurement of a beam's path.

On 26 February, three observers see a flash and then a headlight-like light moving in a semicircle towards them. One of the observers thinks of a snowmobile. They may be right; they have no evidence to confirm it.

If the headlight explained this episode, it would not necessarily explain the red point beside the caravan or what Jon and Ruth saw near the radar echoes. These are different scenes, and each one calls for its own check.

During the month-long campaign, the report collects one hundred and eighty-eight reports. Eighty-six are classified F1, the category for known lights, illustrated in the report with aircraft. One hundred and thirty-five fall overall between F1 and F4; fifty-three fall between F5 and F10. The F scale is a subjective assessment by two people, not a count of new phenomena that have been verified.

The radar records thirty-six tracks. Only three are considered probably coincident with a light seen by people at the same time. Seven spectrographic films are examined and four show a spectrum, with two weak signals; a technical summary uses a different count and speaks of twenty-three photographs, three of them good enough to learn something. The units are not directly comparable.

The laser attempt remains suggestive, but it is not a blind test recorded automatically. Erling Strand's final report says that the team did not discover what the phenomenon was and asks for further observations.

The first lead is ordinary: aircraft, headlights, stars, snowmobiles and reflections seen in difficult conditions. It has eighty-six F1 reports on its side, and the 26 February case, in which a snowmobile is considered possible. But it has a problem: an explanation for one light does not become an explanation for all of them. The snowmobile headlight does not identify what Leif says he saw on the snow.

The second lead begins with the photographs. In 2006, Matteo Leone proposes that a recurring light photographed by the EMBLA mission could be explained by car headlights. It is a concrete hypothesis: Leone compares the headlights with the geometry of the road. But he also points out that there are not enough dates and times for a complete independent triangulation. Massimo Teodorani replies that the headlights and the photographed light could have been different sources, in different positions. Without better synchronisation, the photograph cannot settle the dispute.

The third lead looks beneath the valley. A 2024 geophysical study identifies conductive zones associated mainly with sulphides and structures linked to gabbros. This is a context compatible with the idea that the ground may play a role. The decisive step is missing: no one has followed a single light, at the same moment, to a specific underground anomaly. The map opens a question; it does not provide a cause.

Then there are the suspicions and the more distant hypotheses. The project received technical support from the Norwegian Defence Research Establishment: the report says so in its acknowledgements. That makes the collaboration documented; it does not make it a secret military experiment. To support the suspicion, we would need a trace of the proposed activity; the existence of a consultant is not enough.

None of the original sources consulted identifies an extraterrestrial origin. J. Pascoli has even proposed a wormhole, declaring his idea speculative and asking for higher-resolution spectra. It is a suggestive possibility, but the very measurements that could test it are missing. Today it does not explain the lights we have followed.

Back to the Ford on 20 December 1981. Nils has gone to pick up Per, and now the light is in front of both of them. Per sees it too; then they continue towards Rugldalen, stop and get out, and the light disappears.

The second person makes the testimony stronger, but does not identify the source. This is the most honest measure the case allows: some lights have ordinary explanations, others remain unidentified, and the scenes do not yet form one demonstrated phenomenon. Hessdalen does not leave us an object we can name. It leaves us an archive of people who saw, called, photographed, aimed a laser and tried to reconstruct what was in front of them.
