In March of 1944, the magazine Astounding Science Fiction published a story about a futuristic super bomb. Alarmed counterintelligence officials investigated and established to their satisfaction that the article was speculative and based only on unclassified sources. Years later though it was revealed that the editor of Astounding had commissioned the story because he noticed that numerous scientists who were subscribers had changed their mailing addresses to New Mexico. This led the editor to surmise that some sort of major, physics heavy, technical weapons development was underway there, with an atomic bomb the most logical explanation.
Whether the Manhattan Project or UFOs or other subjects, as a general rule, intense secrecy can keep details secret, but secrecy itself inspires speculation and offers clues as to what the secrecy is attempting to protect. Clever, well-informed outsiders can then guess but not quite prove the essential truth of the secret. That seems to be where the UFO subject is these days -- with DeLonge perhaps poised to trigger the release of enough details to prove that some UFOs are real physical objects of extraterrestrial origin.
Ominously, in the Coast to Coast AM interview, DeLonge also remarked that UFO secrecy was of waning value because the US government had been able to develop the means to defend the planet against UFOs of an aggressive and unfriendly nature. If that is true, our understanding of our place in Creation is going to become a lot more complicated.
Thanks. Very well put, imho.
