The 1946 Swedish Ghost-Rocket Wave

Record summary

From spring through late 1946, Sweden recorded many reports of rocket-like objects crossing the sky or falling into lakes, often called ghost rockets. Swedish military authorities investigated a number of cases and considered possibilities including Soviet tests, meteors, aircraft and psychological or observational error. The wave matters for UAP comparison because it combines civilian reports, military intelligence, geopolitical anxiety and attempted official classification. It is a well-documented historical reporting episode, not proof of exotic vehicles. Individual cases vary greatly in evidential quality and should not be treated as interchangeable.
