The Mjosa ghost rocket

In July 1946 witnesses in Norway reported a rocket-like object crashing into Lake Mjosa. Accounts differ on whether it happened at night or at noon on 18 July.

An Aftenposten report says a man from Feiring told the paper that two rocket bombs had crashed into Lake Mjosa the night before. By that account they looked like small ordinary planes with a wingspan of about two and a half metres. They came between midnight and half past twelve from the west, low over the southern part of Feiring, where many people saw them, among them people at Arnes and guests at the Hasselbaken Inn. The front one showed no light. Witnesses first heard a piercing whistle and then the objects flew into view at terrific speed.

A later compilation by Ole Jonny Brænne dates it to Thursday 18 July 1946, around noon, in the half hour after twelve. Several witnesses saw a V1-like object arrive low, roughly 50 metres up, heading in from the west with a whistling sound unlike aircraft they knew. It flew low enough to sway the trees and hit the lake seven kilometers from Minnesund and two off the western shore, where the water is 300 to 400 meters deep.

NICAP says the wings appeared to flutter like fabric, and that witnesses saw no flame, exhaust or light. Water splashed several meters up when it hit, with no explosion. Press reports of the time say Norway's Defense High Command investigated, though the papers have never turned up.
