Pentagon releases new UFO files with a Roswell witness describing alien bodies and a 'black triangle' over a US site

The Roswell witness is believed to be former base press officer Walter G Haut, whose 2002 statement was kept secret by the Pentagon. He said he saw an egg-shaped craft and bodies about four feet tall with oversized heads in a guarded hangar called 'Building 84'. A separate FBI report says two agents saw a hovering black triangle near a western national security site in June.

Three Boy Scouts reported a silver object outpacing a jet over Catalina Island in 1952.

Utah residents described a 'skinwalker' with a dog's head and a human-looking nose.

SETI Institute chief Bill Diamond urged the public to treat the files 'with a grain of salt'.
