Dyatlov Pass Incident - Russia 1959
In February 1959, nine experienced Soviet ski hikers died under mysterious circumstances in the Ural Mountains. The group, led by Igor Dyatlov, cut their way out of their tent and fled into extreme cold, with some bodies later found with inexplicable injuries. After decades of speculation, a 2020 Russian investigation concluded that a slab avalanche and poor visibility led to their deaths from hypothermia, a theory further supported by scientific research in 2021 and video evidence in 2022. The case, however, remains a subject of public fascination and debate.

Petr Bartolomei, a friend of Igor Dyatlov, proposed a technogenic catastrophe involving rocket testing and nitric acid effects as the main cause of death. Separately, a conference highlighted Igor Pavlov's theory, which suggests the presence of geologists and pilots linked to Li-2 jet aircraft testing.
Josh Gates' investigation into the Dyatlov Pass incident uncovered a metal panel near the site, which tests suggest is an aluminum alloy used in missile construction. This finding introduces a new potential lead regarding the cause of the hikers' deaths.
