The following incident is reported to have occurred one night in 1968 in the Russian Far East on the Amur River in the Primorskiy Kray region.
This sighting was brought to more public attention by researchers Albert S. Rosales and David Weatherly.
"Because of the tense relations between the USSR and China at the time, Soviet KGB frontier troops intensified their patrols in the territories of the Russian Far East which bordered the People’s Republic of China. One night the crew of a Soviet patrol boat on the River Amur spotted a suspicious object flying in from the Chinese bank of the Amur. When the strange object came closer the men on the boat realized that the object resembled a winged human figure. The wings were visibly flapping in the air as the entity flew overhead.
At the moment that the winged figure crossed the frontier into Russia the frontier guards opened fire with their automatic weapons. The flying entity stopped moving its wings and glided down sharply to the nearby taiga and dense pine forest. The crew of the patrol boat radioed headquarters about the incident and the order was given to find the object or creature whatever it was. The KGB frontier guards suspected that the figure was probably a Chinese spy, wearing some kind of flying apparatus or equipment. However a thorough search which included dogs conducted by the frontier guards proved fruitless. The mysterious flying man had disappeared."
