UFO Historian Art Campbell shared details about a UFO crash on the Plains of San Augustin, New Mexico which reportedly occurred the same time as the Roswell Incident in July 1947. Both episodes were likely due to the same air collision, he said, noting that San Augustin is 165 miles west of Roswell. The discoverer of the crashed object in San Augustin was an engineer named Barney Barnett-- while at the site, he ran into an archeological team that later denied they were there, Campbell recounted.
Barnett described seeing a disc-shaped craft that was 25-30 ft. in diameter, which was split on the side. Dislodged from the vehicle, were 3-4 bodies. In what was perhaps the first description of the "greys," he described seeing hairless 3?-4 ft. beings in gray jumpsuits with oddly set eyes. Barnett thought initially they might be connected with the atomic energy field before realizing they were "not of this Earth."
While Campbell was investigating the site beginning in 1994, he collected some interesting evidence, including a biomorphic object he dubbed the artifact which he was told was made out of high-density polyethylene. He also found curious tiny shoe soles which might have been worn by the ETs.
