Incident at Dyatlov Pass

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.
