Several investigators from the National Investigations Committee on Aerial Phenomena (NICAP) researched the photos and they were even published in the local newspaper on September 20,1965. For three years professional photographic analysts studied them using the best technology at the time, but could not prove the photographs as a hoax.
Heflin was interviewed by several government agencies including the Air Force who conducted an inquiry on behalf of "Project Blue Book".
Eventually, on September 20, 1965, Heflin was visited by two men in civilian clothes. A meeting arranged by a man describing himself as a NORAD colonel. The two men took the photos and agreed to make copies and return the originals. The photos were never returned and upon trying to track them down, NORAD disclaimed any knowledge of their existence.
