Scandinavian ghost-rocket wave

Record summary

What happened Thousands of reports described missile- or rocket-like objects crossing Scandinavian skies, sometimes apparently entering lakes. Swedish defence authorities investigated amid concern that the Soviet Union was testing captured German technology. Searches recovered no confirmed missile, though some observations remained unidentified after obvious meteors and aircraft were removed. Evidence Military files, radar and visual reports, press accounts and lake searches document the wave. Explanations considered Meteors, aircraft, balloons, astronomical objects and post-war weapons anxiety explain many reports; secret testing was considered but not demonstrated. What remains uncertain The count combines reports of very different quality and appearance, and no recovered object links them. Primary source Scandinavian ghost-rocket wave — Wikipedia
