This PDF is a CIA memorandum summarizing a debriefing of four people who reported seeing a "flying saucer" or "unconventional aircraft" in 1955. The group included U.S. Senator Richard Russell, a U.S. military service member, and two U.S. Government officials, and they saw it from a train in the Soviet Union, in present-day Azerbaijan, between Baku and Tiflis, now Tbilisi, Georgia.

They described a luminescent "greenish-yellow" phenomenon. The memorandum concludes that the sighting 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."

Declassified by the Department of War under the PURSUE UAP records release (tranche of 7/10/26).
