"An account of a mysterious 'green cloud' sending out powerful shafts of light and flying in tandem with an airliner appeared in a Soviet newspaper today. The strange cloud was seen over Byelorussia by passengers and crew of a flight from Georgia to Tallinn, and by the crew of an airliner from Leningrad, passing 10 miles away according to Trud. Nikolai Zheltukhin, a corresponding member of the Academy of Sciences, said the object was certainly very big. He rejected the idea that the green cloud was an image caused by far-off atmospheric changes because the airman had fixed its location from the shafts of light it sent to the ground."
