Report on Aerial Observations and Search Operations at Mälsten and Kölmjärv

This document, likely a military or intelligence field report, details several observations and search operations related to unidentified aerial phenomena in Sweden and Finland. The primary incident occurred on August 5, 1948, at Mälsten, where a witness named Haglund observed a spool-shaped object using a 4-meter stereo measuring instrument. The object was described as cigar-shaped, approximately 25 meters long, with no wings, and was observed emitting black smoke rings from its rear. It traveled at an estimated speed of 400 meters per second at an altitude of 100 meters. The report also notes that Colonel Jacobsson reported similar smoke ring observations in Finland without a visible object, prompting the FOA (Swedish Defence Research Agency) to investigate if V-2 rocket principles could explain the phenomenon. Additionally, Professor Ljunggren suggested that rotation could provide necessary lift for such projectiles. The document concludes with an update from Major Ahlgren regarding the termination of search operations at Kölmjärv on August 10, 1948, which resulted in no positive findings. Personnel and equipment were subsequently relocated to Gällivare, and further searches at Kölmjärv were deemed unnecessary.
