Forbidden knowledge: Don't ask, don't tell.

"Most critical to this discussion, however, is the 1962 report to President John F. Kennedy from the National Aeronautics and Space Administration (NASA) scientist Dr. Gordon MacDonald that stated, “If the astronomical data are reduced, it is found that the data require that the interior of the moon is more like a hollow [sphere rather] than a homogeneous sphere.”

Upon Kennedy verifying MacDonald’s claim that the Moon was hollow, he demanded, in two separate letters that both NASA and the Central Intelligence Agency (CIA) release to him all “files and information” related to UFO’s barely 10-days before he was assassinated in Dallas, Texas on November 23, 1963.

In a CIA memo rescued by a still anonymous agent from being burned by the intelligence agency, John McCone (1902-1991) the CIA director in 1963 wrote in response to Kennedy’s demand for UFO information, “As you must know, Lancer [Kennedy’s Secret Service code name] has made some inquiries regarding our activities, which we cannot allow. Please submit your views no later than October. Your action to this matter is critical to the continuance of the group.”

This now infamous “Lancer Memo,” a part of what are called “The Majestic Documents,” was sent to the renowned American physicist and aeronautical engineer Dr. Robert Wood, the former deputy director of the major aerospace manufacturer and defense contractor giant McDonnell Douglas, and whose examination of not only this document, but many others related to a massive US cover-up of UFO’s."
