Official who ran secret government UFO program: 'We may not be alone

For decades following the mysterious Roswell incident, Americans have wondered: Are we alone in the universe? Do aliens exist?

Now, the man who led a secret government program to investigate UFOs reveals where nearly a decade of UFO expertise has led him.

What did he say?

Luis Elizondo, who ran the secret investigation from the fifth floor of the Pentagon, told CNN on Monday that he has enough reason to believe that “we may not be alone."

“I can’t speak on behalf of the government,” Elizondo said, but “my personal belief is that there is very compelling evidence that we may not be alone — whatever that means."

“I will tell you unequivocally that through the observations, scientific-methodologies that were applied to look at this phenomenon that these aircraft … are displaying characteristics that are not currently within the U.S inventory nor in any foreign inventory that we are aware of,” he explained.

The secret program was not classified, but it was kept under tight seal. Its existence became public over the weekend when Politico and the New York Times broke the story. The program attracted attention because Elizondo resigned his position from the government in October. Elizondo was a career government intelligence officer.

In his letter of resignation to Secretary of Defense James Mattis, Elizondo said the efforts of the program weren't being taken seriously enough. The program ended sometime in 2012.
