New video evidence appearing to show US military pilot intercepting a mysterious unidentified flying object has shocked US intelligence officials, who have suggested it points to the existence of "an alien civilisation".
The eerie declassified video reveals the moment the US pilots spot the mysterious oval object, which does not have any visible flight technology.
In the mysterious video, the pilots themselves are astonished and stunned by the sight, with one pilot even saying "What the f*** is that?".
Pilots of the American warplane record the flying object, which moves faster than any known US Air Force aircraft along the US East Coast at an altitude of 7,500 meters.
