Sergeant Stone tells an amazing story about the history of UFO's and extraterrestrials dating back to the early 40's and probably before. General Douglas MacArthur organized a group called the Interplanetary Phenomena Research Unit back in 1943 to study this issue and it continues to this day. Their purpose is to recover objects of unknown origin particularly those that are of non-Earthly origin. They obtain field intelligence information and pass it on to those who are the "keepers of this information." This unit was thought to be working in conjunction with Bluebook but in fact was not.
