Soviet Pereslavl-Zalessky: Mass UFO Sighting, Interceptor Scrambled March 21
On the night of March 21, 1990, between 8 PM and midnight, unknown objects are seen over a wide area east of Moscow encompassing Pereslavl, Zalessky, Novoselye, Zagorsk, Yakovlevo, Ploshevo, Dubki, Kablukovo, Fryazino, and Kirzhatch. Radar stations placed on alert and aircraft dispatched. At 9:19 PM, a watch post in Zalessky sees an object with red lights approach from the west at speed 'much greater than any plane.' Colonel A.A. Semyonchenko scrambles at 9:38 PM, tracks the UFO on radar at 2,000 meters altitude above Pereslavl-Zalessky. At 10:05 PM he approaches within 500-600 meters, sees two white flashing lights and the silhouette against the city below. The UFO evades repeatedly — disappearing, reappearing behind and above his jet, playing 'cat-and-mouse games.' Captain V. Birin describes it as a flying saucer 100-200 meters in diameter with bright edge lights and a porthole. General Igor Maltsev, Chief of Soviet Air Defense Forces, states: the disc performed S-turns horizontally and vertically, hovered, flew 2-3 times the speed of modern jets, was 'completely devoid of inertia' and 'had somehow come to terms with gravity.' Deputy Minister of Defense Ivan Tretyak says the pilots refrained from attacking because 'it might have possessed a formidable capacity for retaliation.' Over 100 visual observations and two photographs by military personnel. Reported in Soviet press, translated by CIA's FBIS, copies sent to Joint Chiefs of Staff, FBI, and Navy.
Background
On the night of March 21, 1990, unknown objects were observed over a wide area east of Moscow, encompassing multiple cities and towns including Pereslavl, Zalessky, Novoselye, Zagorsk, Yakovlevo, Ploshevo, Dubki, Kablukovo, Fryazino, and Kirzhatch. The sightings prompted an official military response, with radar stations placed on alert and aircraft dispatched to investigate.
The Incident
The mass UFO sighting began on the evening of March 21, 1990, between 8 PM and midnight. Unknown objects were reported across a broad geographic area east of Moscow, spanning numerous cities and towns in the region.
The sightings were significant enough to trigger a coordinated military response. Soviet radar stations were placed on high alert to track the unknown objects, and military aircraft were scrambled to investigate the phenomena at 9:19 PM.
Investigation
The Soviet military took the incident seriously, implementing standard protocols for unknown aerial phenomena. Radar facilities in the region were activated to monitor and track the objects, while interceptor aircraft were dispatched to conduct aerial reconnaissance of the affected area.
The military response indicates that the objects were detected on radar systems and posed enough of a concern to warrant immediate investigation. The coordinated nature of the response across multiple locations suggests the phenomena were widespread and persistent enough to maintain official attention over several hours.
Significance
This incident represents one of the documented cases from the period of Soviet openness that preceded the collapse of the government, when previously classified UFO encounters began to be reported more openly. The mass nature of the sighting, covering multiple population centers across a wide geographic area, distinguishes it from isolated single-witness events.
The official military response, including radar tracking and aircraft scrambling, demonstrates that Soviet authorities treated unidentified aerial phenomena as legitimate security concerns requiring immediate investigation. This case fits within the broader pattern of military UFO encounters reported from both Eastern and Western sources during the Cold War period.
