I wasn't previously aware of this incident dating from 1959 until I saw an article on Auntie's website.
It has everything for the CT aficionado - Russia, 9 dead young people, radiation (?), KGB/CIA (?), cover up (?), alien abduction (?), military secret testing (?), torture (?) by local tribesmen angered by the group's intrusion onto sacred lands (?), mutilation of the bodies (but only some of them - how weird is that?), several official investigations including one announced only last year that has already, prior to the investigation starting, determined that the cause of death can only be one of three possible (natural of course) reasons, and yeti (?).

Consider it my gift to CT folk to knock themselves out.
