From Truman to Obama, our modern day Presidents have all had rich and controversial histories with UFOs and extraterrestrials. In fact, Eisenhower, Nixon, Carter, and Reagan are each rumored to have had personal encounters. Inside HANGAR 1, MUFON files ask, "What do our presidents really know about the existence of UFOs?" Are some Presidents kept in the dark because they aren't trusted with that knowledge and how they might use it? Or, are they all aware, but the secrets are too dark and deep that full disclosure becomes a risk they just can't take?

Hangar 1 files suggest that beneath mountain ranges, deserts and perhaps even one public airport, there exist Deep Underground Military Bases that are rumored to be the nerve center for some of the U.S. military's darkest secrets. Activities rumored to take place in these underground bunkers involve the study of UFOs, alien life, and black project technologies. MUFON also exposes new, shocking files that reveal an alliance might exist between our government and an underground alien civilization. Is the U.S. government housing UFOs in these underground bases and could extraterrestrials already be living here on earth? We already look to the skies for proof of the existence of UFOs, but perhaps we should also be looking below our feet.

Could the greatest inventions of the twentieth century and beyond potentially be the products of reverse engineered alien technology? Inside Hangar 1, MUFON files trace mankind's technological boom to materials reportedly recovered from UFO crashes in the 1940s. MUFON investigates allegations of alien engineering, from the birth of the transistor in the 1950s, to military UFOs in the Middle East. Is our modern world built on a foundation of borrowed--or stolen--technology?
