Approximately 200 reports of unidentified flying objects reach the non-profit organization Ufo Sweden every year. Most of them deal with different types of light phenomena that have been observed during the evenings and nights.
Many of them can be explained by stars, planets, satellites, planes or other things, says Johan Gustavsson of Ufo Sweden and project leader for the door knockout that will take place this weekend.
Every year there are also one or two reports that can not be explained and that capture the interest of the enthusiasts. The explanatory models are many, where untapped natural phenomena are one of the favorites. On the other hand, Gustavsson turns against theories concerning beings from space.
Personally, I am very skeptical as a statement. On the other hand, I think there is a good chance that there are real unexplored phenomena that today's research is not familiar with.
Discus shaped vessel
The supposed observations in Björkvik 29 years ago, however, for the thought of the more classic description of a flying saucer: a disco-shaped vessel, estimated at at least five meters in diameter, hangs freely in the air. Before the object, which has three flashing lights below, disappears, the witnesses see a hole underneath and a dome on the top. And besides the two most important witnesses, several other people in Björkvik have experienced that they looked something like this.
The event is noticeable. That two credible, sensual witnesses see a formatted object up close and that information about more witnesses is very rare, says Gustavsson.
At the same time, there is a risk that a new testimony may be colored by the fact that the event is well known and known in society.
That is how it is. The new witnesses will never be completely independent.
All answers that come in – that reinforce the earlier observations or testimonials that make the event possible – are gains, says Gustavsson.
That would be a positive result in both cases.
Condenser beams and northern lights
The Total Defense Research Institute (FOI) also receives calls for unidentified flying objects, even though it is rare. According to the FOI analyst Kristofer Hallgren, the statements are meteorological.
For example, it could concern condensation stripes of aircraft that give shadow effects, he says.
At the same time there are cases in which science can not give an absolutely certain answer. New types of weather phenomena can occur, for example when the climate changes.
We as researchers do not have answers to everything, such as weather phenomena. Recently a new type of northern light was found. It is a phenomenon that has existed for a long time, but as previously not classified, says Hallgren.
