Russia's Dyatlov Pass Incident explained by modern science?

swellconvivialguy writes: Fifty-five years ago today, nine young Russians died under suspicious circumstances during a winter hiking trip in the Ural mountains. Despite an exhaustive investigation and the recovery of the group’s journals and photographs, the deaths remained unexplained, blamed on “an unknown compelling force.” Now American film and television producer Donnie Eichar believes he has solved the mystery of the Dyatlov Pass Incident. Working in conjunction with scientists at the National Oceanic and Atmospheric Administration in Boulder, CO, Eichar developed a theory that the hikers died because they panicked in the face of infrasound produced by a Kármán vortex street.
