Disk-Shaped Soviet Aircraft Observed Near Moskva

This document consists of a Project 10073 record card and an associated memorandum regarding a sighting reported near Moscow, USSR, on March 19, 1958. The initial report originated from a Radio Moskva broadcast, which described a 'curious' flying object observed at an altitude of 3,000 meters. Eyewitnesses described the object as a large disk that performed a spiral maneuver at low altitude before departing. The intelligence assessment, prepared by Captain Anthony M. Klasinski of the 7050th Air Intelligence Security Group, concludes that the object was not an unidentified aerial phenomenon in the traditional sense, but rather a Soviet aircraft equipped with a 'round wing.' The report highlights that this specific aircraft design is characterized by its stability, maneuverability, and, as noted in a follow-up card, its capacity for vertical takeoff. The document includes a routing slip indicating that this information was compiled in response to a specific query from a Dr. Shelton regarding 'flying saucer' reports originating from within the Soviet Union. The author notes that the information received from the USSR does not constitute 'saucer' reports, but rather identifies unidentified aircraft or indications of Soviet aviation activities. The report is classified as unclassified and was finalized on July 30, 1958.
