In 1990, the journalists of Moskovsky Komsomolets set up an interesting experiment. On April 1, an article "500 meters to contact" appeared on the front page of the newspaper, illustrated with a clear photo of the "plate" (two plates were borrowed from the dining room and, tying one to the other, hung on a mop).  In the comments to the picture, they asked the eyewitnesses to respond to this and no other plate. In two months, about three hundred "eyewitnesses" of this particular UFO called the editorial office, and about a hundred more sent an accurate description of it, which practically did not differ from the description in the newspaper.
