UFOs: Investigating the Unknown Episode Rating Graph

An explosive congressional hearing reignites a decades-long fight for government transparency on UFOs. A whistleblower provides explosive testimony. Fighter pilots and military personnel describe strange sightings, and the U.S. government is forced to consider a new approach to how they analyze and make public UFO sightings.

Area 51, a military outpost in the desert, shrouded in secrecy for decades, has long been the focus of many Unidentified Aerial Phenomena or "UAP" rumors. A pop culture phenomenon, Area 51 prompted one Facebook group to suggest storming the facility in search for answers. Civilian UAP groups continue making progress in providing those answers. For the first time since 1969, Congress questions high level officials in the Pentagon on UAPs.

From a 1986 sighting over Alaska by Japanese Airline pilots, to a 1997 UAP sighting over Phoenix Arizona and a flying disc over the Chicago O'Hare airport in 2008, hundreds of witnesses come forward without any official feedback from the US government. Years later, many of the pilots and government officials, who witnessed these sightings, come together for the first time to share their story in a 2007 press conference.

No longer waiting for the government to reveal everything they know about UFOs, citizen scientists and privately funded organizations are making advances in data collection. In the air and under the seas, exploration continues to push for answers to the ultimate question: Are we alone?

For as long as there have been sightings of strange objects in the sky, there have been reports from those who say they've encountered entities associated with the phenomena. Despite the stigma attached to speaking out, people share stories of their extraordinary interactions.

Scientists across academia take matters into their own hands, employing a variety of cutting-edge tools to study UFO phenomena. Using AI, precise radar systems, advances in physics and analyses of historical images, they hope to collect data that reveals the source of these mysterious sightings.
