There are actual documents coming to light in the past week that say it's a possibility. Watching this happen is almost an out-of-body experience for me.
Relating Kennedy's assassination to his desire to tell the world the truth about extraterrestrial visitation was, in fact, the central organizing premise of my UFO-themed TV series Dark Skies (co-created with Brent Friedman) that ran on NBC from 1996-1997. On one level, it's true that Brent and I conceived the idea of JFK's death being connected to UFO disclosure as a way of putting the two most compelling modern conspiracies -- the JFK public execution and the UFO cover-up -- into an atom collider, thus creating the Ultimate Conspiracy. But it was more than that. We both accepted the validity of the Roswell event as the crash of a piece of technology that came from some place that wasn't here on Earth. And, if you accept that premise, then the world as we knew it in the 1950s and 1960s (through today, of course) is simply not the same as it appears. For us, that included the Kennedy assassination. As the series log-line stated: "History is a lie."
Now, almost a decade and a half later, the breaking news seems to be that maybe we were a lot closer to the truth than we thought. The best summary of it to date comes from Lee Spiegel of AOL News in a new column. I'd urge you to read Lee's thoughtful examination over some of the other versions getting traction on the Internet, specifically the coverage from the Daily News.
I remember vividly thinking in 1995 that it was possibly one of the most subversive acts ever propagated on an American television network -- devoting 20 hours of programming, produced at a cost of over $40-million, to the theory that President Kennedy died over UFO disclosure. Even as the executives who sponsored us at Columbia TV then at NBC gave us the greenlight to series, none of them really believed the concept. For them, it was just "pushing the envelope" to get an audience.
Now, some researchers are taking this premise seriously. Certainly no one is embracing the every detail of what we did in Dark Skies. It was obviously fiction, designed to attract an audience. But people are talking about the Big Picture idea and saying that it might just have some merit to it.
