Newly declassified documents are providing the opportunity for a deeper investigation into whether governments around the world are engaged in a cover-up of UFO research. MysteryQuest's expedition and science teams travel to locations in the Nevada desert and in Utah to investigate. Using state of the art technology, they investigate these covert US government sites looking for clues about what the government may know. And they experience just how much the government wants to keep its secrets when military helicopters and a fighter jet shadow the team on their trek near the base.

In the 70 years since the famed Roswell UFO crash, there is a long history of allegations involving alien phenomena and their supposed government cover-ups. This special takes a hard look at the most famous, and lesser known, UFO reports that some believe have been purposely hidden from the public.

In 2013--after decades of secrecy, denials, and cover-ups--the CIA declassified documents that acknowledged the existence of a top-secret military research facility known as Area 51. But despite this disclosure, six years later in 2019, millions responded to an internet post advocating to storm the gates. Why does this Top-Secret location continue to draw so much attention--and suspicion? What really goes on within its heavily secured walls? Should we be reassured by its existence? Or fearful?

Are governments around the world preparing mankind for the most startling event in human history--the official disclosure of extraterrestrial contact? Or even an extraterrestrial presence on Earth right now? And if so, why is this happening now, what form might the announcement take, and what might happen in its aftermath?

A mysterious, stark terrain, 90 miles north of Las Vegas, goes by many names: The Box, Paradise Ranch, Groom Lake, Watertown Strip, and Dreamland. But most refer to the region as Area 51. Since the late 1950s, an array of UFO sightings has been reported above its skies. In 1989, revelations of Las Vegas resident Bob Lazar brought Area 51 to national attention. Lazar claimed to possess amazing inside information, but he wasn't the first to state that something strange was going on. Those who discount Lazar's theories think the government kept its activities from the general public for a more plausible reason. The base, built at the Cold War's height, housed testing of cutting-edge aviation technology. The cloak of secrecy was to keep the Soviet Union in the dark, not the American public, and experts expostulate that the government perpetuated these theories to disguise its real activities.

What came down in the forest outside the sleepy hamlet of Kecksburg, Pennsylvania on December 9, 1965? Some residents claimed to see an acorn-shaped metal object with strange, hieroglyphic writing on its side, half-buried on the forest floor. Astronomer Von Del Chamberlain wrote that the Kecksburg object was a meteorite. NASA consultant James Oberg theorized that it was a failed Russian probe, but now also thinks it was probably a meteorite. Often called the "Pennsylvania Roswell" in UFO circles, the debate raged until, in late December 2003, NASA finally released 39 pages of material, and the Air Force released 2,800 pages on the case from its files. The only thing the government documents conclusively prove is that the object was not a Russian probe. But for UFO enthusiasts and researchers, many questions remain unanswered.

What really happened in Roswell, New Mexico in the summer of 1947? Did a flying saucer crash in the vast desert scrubland? The initial Army Air Force press release claimed they had recovered a flying disk. But a day later, the story dramatically changed--now they called it a weather balloon! In 1987, secret documents surfaced indicating the existence of the "Majestic 12"--an elite group of scientists and military and intelligence officials, allegedly brought together by President Harry Truman. Did the MJ-12 truly exist? If so, did these men forever trivialize the most talked-about UFO event in history, as well as all UFO sightings thereafter?
