UFO files live: New documents reveal declassified ‘sightings’ as critics accuse Trump of propaganda with release - Defense Department will share more information about the ‘unidentified anomalous phen

Over the last decade, since the work of a shadowy government program called the Advanced Aerospace Threat Identification Program was made public in 2017, there has been growing public pressure on the US government to release its files related to aliens. At the same time, UFOs have been rebranded as Unidentified Aerial Phenomenon, or UAP.

A famous 'alien' photo, recently circulated as declassified material, has been traced back to a 1950 hoax, fuelling scepticism about the alien claims the Pentagon had been teasing for release.

Barack Obama has cast doubt on alien disclosure. The former president is questioning the government's timeline to reveal UFO footage, saying that any first contact with aliens “hasn’t happened yet.”
