Ghost rockets, Sweden

The three documents supplied for this case do not describe individual Swedish sightings from 1946. Each refers to the Scandinavian events in passing, and none gives dates, locations, witnesses or an investigation of a specific incident.

A CIA memorandum dated 18 December 1952 recorded a conversation between a messenger from Britain and R. V. Jones. According to the memorandum, Jones "reminded us of the Swedish incident", and the author added that he presumably meant the one in 1946. The memorandum was signed by H. Marshall Chadwell, Assistant Director, Scientific Intelligence. It also said a British standing committee had concluded the observations were not enemy aircraft.

A joint USAF and ONI study dated 10 December 1948 mentioned the Scandinavian events twice. On page 6, the study considered whether U.S. reports had been influenced by earlier sightings over Scandinavia in 1946, or by observers seeking publicity. It called these explanations improbable, citing the U.S. Weather Bureau reports from Richmond. On pages 14 and 15, the study discussed a possible Soviet purpose. It stated that strange objects first appeared over the Scandinavian countries in 1946 with unusual range and performance. It also said the U.S. was then campaigning for the alignment of those nations with Western Europe. Its conclusion on that point was that the objects may have been used to frighten both European nations and the U.S.. The study did not say this had been established.

The third document, an English translation of the 1999 French COMETA report held in a NASA file, listed Sweden among countries where other airship cases were reported between 1880 and 1900. That passage concerns the earlier period and does not mention 1946.
