The account
Anatoliy Listratov, chairman of the anomalous-phenomena section of the All-Union Astronomical and Geodesic Society, told Sotsialisticheskaya Industriya (30 September 1989) about an encounter from a pilot's log. He said two Soviet aircraft over Borisov saw a large disc with five beams. One crew was ordered to approach, and the disc aimed a beam at the cockpit, leaving a 20 cm spot of light on a seat; both pilots felt heat. Listratov said the commander and copilot became invalids. He said the commander died within months of cancer, and that radiation from a UFO was listed on the hospital record as a contributing factor. No date for the encounter is given in the US summary.
The sceptical view
The story is known only through Listratov's newspaper interview as summarised by FBIS; no log, medical record or second witness has been published.
