aka Ghost Rockets (1946)

The Swedish Defense Staff opened an investigation in June 1946 after reports began arriving from the Norrbotten and Småland regions. By August the General Staff was receiving dozens of reports per day. U.S. Army Air Forces Gen. James Doolittle and Gen. David Sarnoff visited Stockholm to consult. The Swedish committee’s final report — still partially classified — stated that 80% of reports could be attributed to natural phenomena, but the remaining ~20% (roughly 200 reports) involved objects “of physical reality” that could not be explained.

On 19 July 1946 a cylindrical object was reported to have crashed into Lake Kölmjärv; a military diving team led by Karl-Gösta Bartoll searched the lake bottom for three weeks and recovered nothing, but reported a ‘crater-like depression’ in the lakebed.
