Report on Bomb Impact Incident at Brantshammar

This document is a field report from the Swedish Infantry Shooting School (InfSS) regarding a reported 'bomb impact' that occurred on July 9, 1946, in the vicinity of Brantshammar, 12.5 km north of Sigtuna. The report was initiated following a notification from the Sigtuna District Prosecutor's Office on July 18, 1946. The primary witness, Karl Lunden, reported that he had not initially disclosed the event because he feared he would not be believed. However, on July 18, he discovered physical fragments at the site which he believed were related to the 'bomb' and subsequently reported the matter. Upon investigation by InfSS personnel, additional fragments were recovered. The witness described the phenomenon as a glowing sphere, approximately the size of a croquet ball, displaying rainbow colors and trailing a 2.5 to 3-meter-long glowing tail. The object reportedly moved in a continuous, straight path from a compass direction of 4900, with no observed zigzagging or curving. The witness noted a hissing sound during the object's movement, which became slightly more intense at the point of impact. The report includes photographic documentation of the recovered fragments.
