In 1948, the US government launched several inquiries into UFO sightings, which many believed were sparked by Cold War paranoia.
In what became known as ‘Project Blue Book,’ more than 12,000 encounters with UFOs were looked into by the Air Force.
Now, decades after the files were closed, the microfilms have been made available online for free – allowing anyone to re-examine the evidence.
The USAF says that the Blue Book included 12,618 sightings reports, with 701 of which remained ‘unidentified’ – or around 5.5 per cent of the files.
