Sighting Report: Aerial Phenomenon over Norrbysjön, August 11, 1946

On August 12, 1946, an individual wrote to Captain Olin of the Swedish Armed Forces Air Defense Department to report an aerial sighting that occurred the previous evening. On Sunday, August 11, 1946, at 20:48, the author and his wife were hunting ducks in the northern part of Norrbysjön, located 40 kilometers north of Stockholm. During this time, they observed a blue-white glowing fireball passing over the lake in a northerly direction. The object was sighted 1500 meters north-northwest of Vidbo church. The witness noted that the object appeared to be descending and made no sound as it traveled. The light from the object appeared to extinguish just north of the lake. The author of the letter established his credibility by noting that he has held a civil pilot's certificate since 1936 and has served as a gunnery officer at both the Väddö and Karlsborg military installations.
