There were several sightings of waves of UFOS in the Scandinavian area.
In 1946 precisely on the night of June the 9th, an obvious beam of light was observed over Helsinki, in Finland, with a trail of smoke and thunder sounds; its luminous trail remained for ten minutes. The next day another similar one was observed but it took the opposite direction to which the first one came from.
Three days later, the Swedish military personnel were ordered to report their sightings through official channels, admitting that they had been aware of the phenomenon since May. On July 9 alone, more than 200 reports were received, many of them describing tubular or “spindle-shaped” objects flying low and slowly, with barely audible sound.
A week after the acknowledgment of a special “ghost rocket” committee by the Swedish Government, American Secretary of the Navy, James Forrestal, went to Stockholm to discuss the matter with the Swedish Secretary of War. According to a secret FBI memo of August 19, 1947, “the ‘high brass’ of the War Department exerted tremendous pressure on the (Army) Air Force’s Intelligence to conduct research and collect information in an effort to identify the sightings.”
On August 11, 1946, more than 300 reports of strange sightings were observed within Stockholm area. Following this, on August the 20th, General Jimmy Doolittle (in Stockholm on business for the Shell Oil Company) met with the head of the Swedish Air Force. This led to wide speculation in the Swedish press, as well as The New York Times, that “ghost rockets” were the subject of the meeting. In the 1980s, however, in an interview with UFO researchers, General Doolittle denied that his Swedish trip was officially connected with the “ghost rockets,” although it is certainly likely that the subject came up in casual conversation.
“A large number of visual observations have been obtained from Scandinavia. Some of the best came from Norway. An analysis suggests the most notable characteristics of the projectiles to be: a) great speed; b) intense light frequently associated with missile; c) lack of sound; d) approximate horizontal flight… Thus, if the phenomena now observed are of natural origin, they are unusual; sufficiently unusual to make possible the alternative explanation that at least some are missiles. If this is so, they must be of Russian origin.”
