A newly released DVD featuring a detailed analysis of both official and leaked documents provides a compelling case that President Kennedy's efforts to declassify UFO files was a direct factor in his assassination. The DVD is a video recording of Dr Michael Salla's presentation at the 7th Annual UFO Crash Retrieval Conference on November 7, 2009. Dr Salla reveals that there were three critical periods concerning President Kennedy's efforts to gain access to classified UFO files. The first began in February 1961 with Kennedy's Executive Order to place psychological warfare programs under the control of his national security team.The second period then began and involved Kennedy using his authority as Commander in Chief to learn what he could about UFOs and extraterrestrial life, while being denied access to UFO files by MJ-12 and the counterintelligence (CI) branch of the CIA. The third and most critical period began on September 20, 1963 when President Kennedy gave a speech at the UN General Assembly calling for joint space and lunar missions with the USSR.
