SUGGESTED READING.
Blue Book Special Report 14 and the Project Sign and Project Grudge reports. These primary documents should have been part of this organization’s UFO study files and currently available through the National Archives.
*The UFO Controversy in America*, David Michael Jacobs. Contains a comprehensive review of documents belonging to this organization’s UFO study files.
*The Report on Unidentified Flying Objects*, Edward Ruppelt. Ruppelt was the UFO study project officer from 1951-1953 and he investigated a series of reports from 1947. He found nothing, apparently, about the Roswell incident.
*The UFO Experience*, J. Allen Hynek. Written by the chief scientific advisor to this organization for UFO studies. Associated with Sign/Grudge/Blue Book from 1948-1969, he found nothing, apparently, about the Roswell incident.
*Flying Saucers: Top Secret*, Donald Keyhoe. Keyhoe helped establish NICAP and was one of the earliest to allege that the government was withholding UFO "secrets" from the public. He found nothing, apparently, about the Roswell incident.
*Flying Saucers and the U.S. Air Force*, Lawrence Tacker. States the official Air Force position as of 1960 and includes earlier Air Force statements about UFOs.
