In 1990, the chief investigator, Lev Ivanov, said in an interview that he had been ordered by senior regional officials to close the case and classify the findings as secret. He said the officials had been worried by reports from multiple eyewitnesses, including the weather service and the military, that “bright flying spheres” had been spotted in the area in February and March 1959.
“I suspected at the time and am almost sure now that these bright flying spheres had a direct connection to the group’s death,” Ivanov told Leninsky Put, a small Kazakh newspaper. He retired in Kazakhstan and has since died.
February, 1959, the Ural Mountains in Russia - Ten young cross country skiers from the Ural Polytechnical Institute, eight guys and two girls led by Igor Dyatlov, set out for two weeks of adventure. One became ill and turned back: Little did he know he would be the only one to return alive. Weeks later, searchers found one of the most bizarre scenes in modern lore. The bodies of the nine victims were scattered over a wide area of the frozen landscape. Some were wearing only their underwear. Some were wearing each others' clothes. Two had head injuries. One had no tongue. Two had severe internal chest injuries. None had any visible external signs of trauma. Some of their clothes were found to be radioactive. Circumstances suggested that some the victims may have been blind. Various other witnesses in the region reported bizarre orange spheres in the night sky; and strangest of all, the bodies had orange skin and gray hair.
