I remember some history channel thing, mentioned something about them thinking they were from Atlantis and measured skulls in Tibet. Something about an order that Himmler ran that created a bunch of myths that people believed?
Sub question isn't the guy who rescued Mussolini, Oskar Skorzeny, guilty of some really terrible atrocities?
Not to discourage further discussion but /u/Subs-man and myself tackled the occult question before and there is a section in our FAQ dedicated to this very subject.
And Otto Skorenzy was indeed guilty mainly of the shooting of POWs and of partaking in anti-Partisan warfare in Yugoslavia and the Soviet Union. Especially during the raid on Drvar he and his unit slaughtered captured Partisans.
