UFO Sweden is a non-profit organization that helps the public find explanations for things you see in the sky. With the advent of mobile cameras, reports to the organization have also increased over the past ten years.
At the time of writing, five tons of information are on their way to Sweden from the US and UK. "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 chairman Clas Svahn.
