a distance of around 800 meters, the aircraft he hit was most likely No. A77-17 or No. A77-982, which were damaged in the battle but eventually returned to service. The next day he gained another credited aerial victory; there he led a group of 18 MiGs over Pyongyang, where they intercepted 16 F-84s at an altitude of 4,000 meters at 10:42 AM, which they subsequently dispersed and claimed to have shot down three of. However, it is unclear exactly which aircraft, if at all, that Vishnyakov show down that day. Over the next several days he tallied his last two aerial victories. On 5 December, Vishnyakov led a group of 22 MiGs in intercepting a group of 12 F-80s and 4 F-84s over Dzyunsen. With cover provided by other aircraft in his unit, he pursued an F-84 and shot it down, presumably F-84E 49-2415 piloted by Hugh Larkin, who parachuted out of his stricken plane and declared missing. Several days later on 8 December he claimed his last aerial victory in Korea, having led 20 MiGs from his regiment in a dogfight with 24 F-86s. In the resulting battle, Vishnyakov and two other Soviet pilots claimed aerial victories, but American records indicate the loss of only one F-86 from that encounter, F-86E 50-622, so it is unclear which Soviet pilot or pilots was responsible for it. Throughout the war he flew approximately 100 sorties, engaged in 36 aerial battles, and claimed six aerial victories. Later life and death Initially after returning to the USSR he continued to command his wartime regiment. In January 1953 he graduated from training for commanders and chiefs of staff of aviation divisions at the Air Force Academy. Starting in November 1953 he served as deputy commander of the 324th Fighter Aviation Division, and in February 1955 he became the unit's commander. Subsequently in December 1957 he was appointed as military adviser to the commander of fighter aviation in the Bulgarian People's Army. During that post he was tasked with participating in training flights; during one such flight at night in a MiG-15UTI with a Bulgarian pilot on 10 June 1958, after the plane made a sharp maneuver, the cockpit canopy was torn off, hitting Vishnyakov in the head and killing him instantly. The Bulgarian pilot managed to land the plane safely, and Vishnyakov was buried in Kaluga. Awards Order of Lenin (22 April 1952) Four
