Ghost rockets

Two hundred sightings were verified with radar returns, and authorities recovered physical fragments which were attributed to ghost rockets.

The early Soviet origins theory was rejected by Swedish, British, and U.S. military investigators because no recognizable rocket fragments were ever found, and according to some sightings, the objects displayed some combination of leaving no exhaust trail, moving too slowly, flying horizontally, traveling and maneuvering in formation, and appearing to be silent.

Immediately after the investigation, the Swedish Air Force officer who led the search, Karl-Gösta Bartoll submitted a report in which he stated that the bottom of the lake had been disturbed but nothing was recovered and that "there are many indications that the Kölmjärv object disintegrated itself...the object was probably manufactured in a lightweight material, possibly a kind of magnesium alloy that would disintegrate easily, and not give indications on our instruments".

[citation needed] Of the nearly 1,000 reports that had been received by the Swedish Defense Staff to November 29, 225 were considered observations of "real physical objects" and every one had been seen in broad daylight.

However, the Times story indicated that the Chief of the Swedish Defense Staff made no secret that he "was extremely interested in asking the two generals' advice and, if possible, would place all available reports before them".

(Carpenter chronology)[clarification needed] Doolittle and Sarnoff were briefed that on several occasions the ghost rockets had been tracked on radar.

[2] On August 22, 1946, the director of the Central Intelligence Group (CIG), Lt. Gen. Hoyt Vandenberg, wrote a Top Secret memo to President Truman, perhaps based in part on information from Doolittle and Sarnoff.

CIG speculates that the missiles are extended-range developments of V-1 being aimed for the Gulf of Bothnia for test purposes and do not overfly Swedish territory specifically for intimidation; self-destruct by small demolition charge or burning".

Although the official opinion of the Swedish and U.S. military remains unclear, a Top Secret USAFE (United States Air Force Europe) document from 4 November 1948 indicates that at least some investigators believed the ghost rockets and later "flying saucers" had extraterrestrial origins.

The document ends with the statement that "we are inclined not to discredit entirely this somewhat spectacular theory [extraterrestrial origins], meantime keeping an open mind on the subject".

Later Santorinis told UFO researchers such as Raymond Fowler that secrecy was invoked because officials were afraid to admit of a superior technology against which we have "no possibility of defense".

A ghost rocket or a meteor. Photographer Erik Reuterswärd suspected a meteor was depicted in his widely circulated photo. The Swedish Army , who released the picture, was less certain.
