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?

Inside Hangar 1, MUFON archives contain dozens of reports of UFO crashes--yet few of these incidents ever reach the public. In 1976, a UFO crash along the Gulf of Mexico leads to a confrontation between the U.S. and Mexico, with a deadly aftermath. In the 1800s, a small farm town holds a public funeral for an extraterrestrial pilot of a crashed flying saucer. And in Kecksburg, Pennsylvania, one man's search for the truth behind a 1965 UFO crash may have led to his murder. Who is covering up evidence of UFO crashes, and how far will they go to keep you from knowing the truth?

In the United States, there are certain areas that seem to attract more UFO sightings than others. Missouri has been experiencing unusually high UFO activity for the last three years. One famous incident in the Hudson Valley in New York lasted several months. In addition, every nuclear missile base in the U.S. has experienced UFO visits. What is the common thread that makes these locations a magnet for potential activity? Hangar 1 files reveal the answers...and reveal whether you might be living in the middle of one these hotspots right now.

Hangar 1 files reveal that President Ronald Reagan's personal encounters with UFOs may have been the driving force behind the Strategic Defense Initiative, a controversial program that may have led to a top secret space weapons platform to protect us from attacks from space. Waves of UFO sightings across the world may, in fact, be evidence of a secret fleet of military UFOs that we've created. Has NASA and the U.S. government been secretly building this program to protect us against alien and asteroid attacks? A look into MUFON's files suggests that these space weapons may already be in place.
