Air Force UFO Sighting Reports
Denmark started filing military UFO reports in 1944, three years before Kenneth Arnold made "flying saucers" a household term. The same structured questionnaire was still in use in 2002.
The Collection
The Flyvevaabnet (Danish Air Force) used a single standardised form for the entire programme: SPORGESKEMA Form 3622. Military personnel, police officers, and civilian observers all filled out the same questionnaire. Date, time, location, sky conditions, observer details, description of the phenomenon. Fixed fields. No free text narrative.
The earliest reports cover the final year of World War II. Scandinavian airspace was seeing unexplained aerial activity that military authorities could not attribute to German, British, or American aircraft. The ghost rockets of 1946 intensified Scandinavian military attention. By the time the rest of the world started paying attention in 1947, Denmark already had three years of structured documentation. All documents are in Danish.
The 1944 and 1945 forms describe objects that nobody had a name for yet. No "flying saucers," no "UFOs," no cultural framework to shape the reports. Just military observers documenting aerial contacts they could not explain, using the same form they would still be using half a century later. The ghost rockets of 1946, widely tracked across Sweden and Norway, have Danish counterparts in these files.
NATO Intelligence Markings
The classification marking RCS: CHODDEN INT-20209 runs through the documents, placing every report inside a NATO intelligence channel. A farmer's sighting over Jutland entered the same system as a USAF pilot encounter over West Germany. Denmark is a small country. Its intelligence obligations within NATO were not.
The fixed-field format is the real asset here. Shape descriptions, flight characteristics, weather conditions, observer type: all recorded in the same fields in 1952 and in 1998. That consistency across nearly six decades makes longitudinal analysis possible in a way that free-text narrative archives cannot match.

Flying Saucer Review covered Scandinavian ghost rocket sightings and NATO-era cases. The Canadian CIRVIS logs share the same NATO intelligence reporting channel.

Danish Defence (Forsvaret) - previously hosted these filesLongitudinal Value
The archive is compact compared to American or British holdings. What it lacks in volume, it compensates for in consistency and timespan. One form, one system, 1944 to 2002. NATO intelligence markings throughout. The data is structured enough to query statistically, which cannot be said for most national UFO archives.
Sweden's ghost rockets of 1946 are well documented. The Danish counterparts, captured in these earliest files, are far less known. They show Scandinavian military authorities documenting aerial phenomena years before civilian UFO organisations existed to collect reports from the public.
The Danish Air Force standardised its sighting documentation on Form 3622, used continuously from the 1960s through the programme's closure in 2002. Each form required witnesses to record shape, colour, movement pattern, duration, and prevailing weather conditions. Observer type was a mandatory field: military, police, or civilian. The fixed structure meant that a report filed in 1968 and one filed in 1995 share exactly the same data schema, making cross-decade analysis straightforward in a way that narrative-format archives cannot match.
