This is an essential podcast between Joseph Atwill and Tim Kelly. One character who always turns up at significant moments in history is CD (Charles Douglas) Jackson or Jacobson as his real name was. This is the guy who presented the human lampshades and shrunken heads at Buchenwald which have gone missing and so can't be verified as props for psychological warfare.
CD Jackson also took care of the Zapruder film for the Life Magazine on behalf of the CIA.
He also interviewed Betty and Barney Hill of early UFO abduction fame, who we now think were part of military experiments.
