Thanks, Powerdown and tlr1138 for a great thread. Good investigation, there.
"Who killed JFK," is going to go down in history, as one of the greatest of controversies. To cover every angle of probabilities might be impossible.
I digressed from the thread, sorry about that.
Implications that JFK poked his nose into Area 51 business one too many times, has come forth as one of the many possible motivations for assassination, (among a bushelfull... take your pick!) Who, in the Mafia, the CIA, the NSC, the NSA, didn't have a reason to "off" him? The plot of this story turns into a farce, to try and pin it down.
As for these former spooks/military people coming out claiming they saw aliens running underground bases and experimenting with humans - if they could give us some actual evidence it would be great, but instead we just have to take their word for it. Have you read Jacques Vallee's "Revelations"? It really makes you more skeptical about supposed insiders and the motives for their stories.
Thanks, I'd like to check that one out, by Vallee.
My viewpoint is colored by witnesses in the Disclosure field, who have gathered a lot of testimony. Insiders lived under threat, and often suffered for speaking out. Some of new facts are now in writing. Richard Dolan, (in UFO's and the National Security State,)
did a great job. However, a more controversial viewpoint, is a mythbuster: Exposing U.S. Government Policies on Extraterrestrial Life
, by Michael E. Salla, Ph.D. I consider it groundbreaking, in presenting the evidence that Eisenhower was deeply involved in UFO coverups, in the 1950's. The secrecy haunted him after leaving the presidency, and that was probably why he gave JFK a lot of the inside story. (Testimony exists to that effect.)
As to your reference above, I have the copy of a document which went to the Joint Chiefs of Staff of the Pentagon, edited by a highly-regarded military witness to the "underground mysteries" you describe, tlr. Guess where the witness is? (You guess... either dead, or a political prisoner. That is why there are very few witnesses willing to go "on the record".)
