Investigation Report Regarding Aerial Sightings in Umeå, 1946

This document is an official investigation report dated September 16, 1946, authored by acting criminal constable Folke Johansson of the State Police Department. The report details an inquiry into sightings of 'space projectiles' reported in the Umeå region. The primary incident described occurred in late May 1946, involving Hans Sigfrid Forsberg, a brickworks owner, and two workers, Holger Lundström and Tycko Andersson. While working in a gravel pit approximately 100 meters east of Lake Trehörningen at 15:45, Forsberg heard a powerful, whining sound, which he compared to an airplane flying at low altitude with its engine turned off. Initially suspecting a tornado, Forsberg looked up and observed an object flying from the east, passing just above the treetops of a nearby hill. The object continued in a westerly direction over Lake Trehörningen. Forsberg was unable to track the object further because he was blinded by the sun, which was positioned in the direction the object was traveling. He could not definitively state whether the object crashed into the lake. The document also references a prior report made by telephone to Captain Wall at the Umeå Defense Staff (Fo-staben) regarding this and other recent sightings.
