On 26 February, Finnish and Swedish observers made the first reports of so-called Spökraketer (Swedish for “ghost rockets”). This day can be regarded as the beginning of the global phenomenon of unidentified flying objects, or UFOs, being spotted. The concept went on to have a significant impact on the popular culture of the 20th century.
In Finland and Sweden, unidentified flying objects were initially called missiles. In 1946, there were about 2,000 UFO reports. Investigations concluded that many ghost rocket sightings were probably caused by meteors. It was also assumed that it could be attributed to the launches of captured German V-1 and V-2 missiles from a former German rocket facility at Peenemünde. However, no launches of missiles at Peenemünde have been confirmed after February 1945. On 10 October 1946, the Swedish Defense Staff publicly stated: "Most observations are vague and must be treated very sceptically".
But in July 1947, after the incident in Roswell, in the US state of New Mexico, which journalists named the “flying saucer catastrophe”, the whole world became swept with a new craze - “UFOmania”, an obsession with flying objects of unknown origin. In most cases, UFOs were associated with aliens from outer space, or sometimes with military tests. Numerous UFO groups emerged, dedicated to studying the pseudoscience of UFOlogy. In 1951, the US government launched Project Blue Book to analyze UFO reports and determine if the mysterious aircraft posed a threat to national and global security. In 1961, the programme was deemed a waste of money and shut down.
Characteristically, UFOmania arose at the beginning of the Cold War - as a result of propaganda and popular fears of global wars. Prior to 1945, such sightings had usually been associated with the testing of "Hitler's secret weapon", which he could not use for some reason.
