Incident Report: Sighting in Trehörningen, February 1946

This document contains two separate accounts of aerial phenomena observed in Sweden in early 1946. The first account details an incident on February 26, 1946, at approximately 14:00, in Trehörningen. A witness named Sandström, while working with five other men (Helmer Lövgren, Konrad Johansson, Gustav Jonsson, Oskar Jonsson, and Frans Jonsson) on a water well, observed a smoke formation stretching in a straight line from southwest to northeast. The smoke resembled that of a locomotive. At the northeastern end of this formation, Sandström observed an egg-shaped object at a very high altitude, moving at a high rate of speed. No sound was heard, though the witness noted that stone drilling was occurring nearby, which might have masked any noise. The smoke formation was lighter in color than the surrounding clouds, eventually descended, and dissolved above the treetops within five minutes. Sandström noted that he had not seen similar phenomena before and provided a sketch (Appendix 6). The second account, dated September 17, 1946, by P. Johansson, introduces a witness named Johan Oskar Grehn. Grehn, along with Asel Teodor Andersson and Ingvar Andersson, reported a sighting in late February or early March 1946 at approximately 13:30 in the vicinity of Tavelsjö and Långviken.
