PM regarding observation by former Norwegian officer X

This document is a memorandum (PM) regarding an incident reported by a former Norwegian officer, referred to as 'X', who had been working as a tourist and fisherman in the border regions near Russia during the summer of 1938. On the night between July 8 and July 9, 1938, at 23:35, X was fishing in the Grens Jaakobs elv (Vuoremi joki) near the Kivitunturi mountain range. X reported hearing two powerful detonations, which he described as sounding like explosions. Immediately following these sounds, he heard a hissing, very strong noise, which he compared to a welding apparatus but noted was louder. A narrow, elongated cloud of 'steam and heat' appeared over the part of Kivitunturi furthest from the observer. From this cloud, an object emerged that appeared to be a projectile. The object's trajectory was at a 30-40 degree angle to the horizon, and the distance to the phenomenon was estimated to be 5-8 kilometers. The weather was clear and the sun was up. A fishing companion of X, a former non-commissioned officer in the Norwegian border guard who was located a few hundred meters away, made the same observations. When asked specifically about the size of the object, X estimated it to be 10-15 meters, though he emphasized that this estimate was highly uncertain. X left the border area on July 9.
