"This is the story of the witnesses that were laughed at, researchers and reporters that weren't believed and the government and military personnel that were sworn to silence. A story that alters the foundation of everything you thought you knew...," the video description says.
According to UFO enthusiasts, the footage, being scientifically "verified," offers proof of the existence of mysterious UFO phenomenon.
"The light phenomena here in Hessdalen in Norway started in late '81 with a lot of sightings, at the most it was 20 sightings a week," Strand said. "The local people here started to see the light down in the valley, sometimes close to their houses and they were wondering what this could be."
Governments maintain top-secret programs to study the phenomenon using ground and airborne military radar facility. Official investigations of reports by credible witnesses are also conducted.
Hundreds of credible witnesses, including civilian and military pilots, have reported sightings. Many UFOs have also been tracked by military radar.
Evidence of government interest in UAPs is revealed in recently declassified UFO files. Some of the documents show that governments are concerned and worried about the implications of UFO sightings to national security.
The Inquisitr reported in February that classified documents released in 2012 by the U.K. Ministry of Defense revealed military officials urging the government to investigate UFOs as a "matter of priority."
"If they do exist we do not know what they are, their purpose or if they pose a threat to the UK," an official wrote. "If the sightings are of devices not of the earth then their purpose needs to be established as a matter of priority."
"Behind the scenes, high ranking Air Force officers are soberly concerned about UFOs," former head of the CIA Admiral Roscoe Hillenkoetter said in 1960. "But through official secrecy and ridicule, many citizens are led to believe the unknown flying objects are nonsense."
"The U.S. Air Force has constantly misled the public about UFOs. I urge congressional action to reduce the danger from secrecy," he added.
The widespread use of phone cameras and the emergence of the Internet has led to widespread reports and documentation of sightings. The Internet is making it increasingly difficult for governments to deny the existence of UFOs, enthusiasts say.
