» RELATED: Wright-Patterson was ground zero for UFO investigations
Here are five things we know about UFOs and their connection to WPAFB:
Wright-Patt was part of Project Blue Book: Project Blue Book was a United States Air Force initiative to investigate UFO sightings that ended in December 1969. Records from the project's findings have been declassified and are available for review within the military records at the National Archives.
The black vault: Project Blue Book records are stored on micrfiche at the National Archives, but California-based UFO researcher John Greenewald has compiled more than 100,000 records from Project Blue Book to provide easier access to the records.
The USAF stance on aliens: In January 1985, the Air Force issued an official denial that Wright-Patterson housed alien space technology and the bodies of beings from another planet. Szymanski said he is convinced that evidence from the controversial crash in Roswell, N.M. in 1947 was brought to the base, but in his 39 years working there he says he never saw any evidence of alien beings.

Is it a bird, is it a plane: According to a report declassified in August 2013 titled "The Central Intelligence Agency and Overhead Reconnaissance: The U-2 and Oxcart programs, 1954-1974," high-flying spy jets U-2 and SR-71 were mistaken for UFOs more than half the time in the late 1950s and 1960s.
