UFO Sweden receives just over one report a day, where it is usually about points of light in the sky that are photographed with mobile cameras.
"But every year there are some cases that are genuinely difficult to explain. There is a core of objects and vessels that can be almost anything, and we are curious about them," says Clas Svahn.
Reports have increased over the past ten years
UFO Sweden is a non-profit organization that helps the public find explanations for things you see in the sky, and the association also has the world's largest UFO archive. At the time of writing, five tons of information are on their way to Sweden from the US and UK.
With the advent of mobile cameras, reports to the organization have also increased over the past ten years. Most can be explained, but it is the few remaining percent that Clas Svahn and his colleagues are very interested in.
"Would have been the biggest news in the history of the world"
"We know that there are unknown phenomena complexes, but we don't know what causes this. If I knew, it would have been the biggest news in the history of the world," says Clas.
