AI-Generated Summary

TL;DR

This document outlines Swedish military radar tracking of unidentified aerial phenomena in July 1947 and the subsequent, unsuccessful search for physical debris in Lake Kölmjärv. It also documents administrative briefings to the Swedish government regarding these events.

This document, labeled 'Blad 2', details military reports and investigations regarding unidentified aerial phenomena in Northern Sweden during July 1947. It begins by summarizing radar reports from air wings F16 and F17. On July 21, F16 tracked an object between 20:51 and 20:55, noting its movement, altitude of 3800 meters, and varying echo strength. On July 24, F17 tracked an object at 20:55 with a speed of 480 km/h. The report notes that these FV ER-indications were not initially submitted to the General Staff (Fst) due to an oversight, but future reporting will be handled by Major Söderlindh. Major Ahlgren confirmed that the government and the Ministry for Foreign Affairs (UD) were briefed on the situation, and a memorandum regarding recovered remains was submitted to the government. The General Staff requested and received 10,000 SEK for related expenses. Engineer Malmberg provided a summary of a visit to reported crash sites in Northern Sweden. While three observations were recorded in a protocol on July 22, an additional observation was made at Lägenön. The only site where an object was reported to have fallen was Kölmjärv. Extensive sonar searches of the lake were conducted without success. Further searches were planned for July 29, involving a search aircraft from KÄFT and a metal detector from Boliden. Engineer Malmberg noted that if these efforts failed, the only remaining option would be to drain the lake, though Officer Dahlgren of Ing 3 advised against this due to the high cost and time involved. Finally, the report suggests that the phenomena observed at Rödupp and Kamlunge may have been caused by whirlwinds, while the observation at Lägenön may have been caused by propeller wash from a motorboat.

De vid 2 (Rödupp) och 3 (Kamlunge) observerade fenomenen kan ha orsakats av tromber och vid 4 (Lägenön) av propellervattnet från en motorbåt.
