Sighting Report of a 'Ghost Bomb' (Spökbomb) — Ingarö, Sweden, August 11, 1946

On August 12, 1946, Commander A. Kull of the Swedish Defense Staff's Foreign Department submitted a report to the Chief of the Air Defense Department regarding a sighting that occurred on August 11, 1946. At 20:47, Commander Kull and his wife observed a luminous object while on the road just south of Säby gård on the island of Ingarö. The object was initially seen at an elevation of approximately 50 degrees, positioned relative to the moon. It moved from this point without a change in bearing, descending toward the treetops over a period of approximately 15 seconds. The object was described as having a sharp, magnesium-white light at its front, which was significantly brighter than the moon. Behind this, a conically tapering section was partially illuminated by a yellowish light emanating from the rear. This rear light appeared to 'dribble' or shed luminous particles, similar to certain types of fireworks. The weather conditions were described as having very good visibility and no wind. No sound was heard, and no distance estimation could be made, though the author noted that the treetops at a distance of less than one kilometer were not illuminated by the passing object. The author concluded that the observation was likely a so-called 'ghost bomb'.
