Memorandum on Unconventional Aircraft Sightings, 1955

Central Intelligence Agency · 1955 · 3 pages · text from the file's own layer

This Central Intelligence Agency memorandum, dated 1 November 1955 and signed by Herbert Scoville Jr. of the Office of Scientific Intelligence, is filed under a Top Secret cover sheet. The body text is badly degraded, but it describes a sighting of an object by travelers, including a Colonel and a Mr. Ritzen (name only partly legible), who watched its flight. It concludes that most such sightings can probably be explained, and says the evidence does not yet support the conclusion that a radically new type of craft has been seen.

From the source: Release of 2026-07-10 Incident: 1955, Azerbaijan. This memorandum summarizes a Central Intelligence Agency (CIA) debriefing of a group of four individuals who reported observing a “flying saucer” or “unconventional aircraft” in 1955. The group, which included U.S. Senator Richard Russell, a U.S. military service member, and two U.S. Government officials, reported observing a luminescent “greenish-yellow” phenomenon, as seen from aboard a train while traveling within the Soviet Union, in present-day Azerbaijan, between Baku and Tiflis (Tbilisi, Georgia). The document concludes by stating that the observation can “probably be explained as steep climbing aircraft or missiles,” and that “the evidence does not appear sufficiently firm to warrant the conclusion that the Soviets have developed […] a radically new type of aircraft.” The document “CIA-UAP-D021” contains a contemporary analysis of the incident.
