In December, a New York Times article revealed the existence of a top-secret US Department of Defense department which investigated the UFO phenomenon for five years from 2007 to 2012.
The Advanced Aerial Threat Identification program (AATIP) had a £16million budget to investigate any threat posed by unidentified objects observed by the military.
It was headed by Luis Elizondo, who resigned from the DoD last October to help set up the To The Stars Academy with former Blink 182 singer Tom DeLonge to further UFO research privately.
The article also revealed radar camera footage from a US Navy aircraft flying off the coast of San Diego in November 2004, which was said to show a UFO that "defied physics."
This footage was part of the so-called Nimitz UFO incident, in which several US Navy personnel reported seeing several tic-tac shaped UFOs over the sea, a case that was investigated by the AATIP.
Mr Elizondo later went on record to say the case, and others looked at by the AATIP, showed "there was very compelling evidence that we are not alone”.
The US-based SETI Institute is a collective of scientists looking for evidence of alien life in the cosmos.
Now, in a radio podcast of the Big Picture Science Skeptic Check, produced at the SETI Institute, a panel of experts looked at the shocking radar video footage.
James McGaha, is a retired US Air Force pilot, astronomer and director of the Grasslands Observatory, who was part of the panel.
He was not convinced the video is proof of anything, let alone aliens.
He said: "People see what they want to see. If you are not trained to know what you are looking at, the brain will fill in the gaps."
UFO believers claim the high number of pilots, astronauts, and police reporting seeing UFOs, means alien craft must exist.
However, Mr McGaha shot this down, saying pilots were not trained observers to astronomical phenomena.
