The National Investigations Committee On Aerial Phenomena was formed in 1956, with the organization's corporate charter being approved October 24. Hillenkoetter was on NICAP's board of governors from about 1957 until 1962. Donald E. Keyhoe, NICAP director and Hillenkoetter's NavalAcademy classmate, wrote that Hillenkoetter wanted public disclosure of UFO evidence. Perhaps Hillenkoetter's best-known statement on the subject was in 1960 in a letter to Congress, as reported in The New York Times: "Behind the scenes, high-ranking Air Force officers are soberly concerned about UFOs. But through official secrecy and ridicule, many citizens are led to believe the unknown flying objects are nonsense."
Built at Puget Sound Navy Yard and commissioned 1918; placed in Reserver, 1930; recommissioned 1941
USS O-2, a 521-ton O-1 class submarine built by the Puget Sound Navy Yard, was commissioned in October 1918. After transfer to the Atlantic, she spent nearly a dozen years operating along the East Coast and in the vicinity of the Panama Canal Zone. O-2 was placed out of commission in June 1931 and laid up at the Philadelphia Navy Yard. The National defense expansion of the early 1940s brought her back to active duty. Recommissioned in February 1941, she was assigned to training duty at New London, Connecticut, during most of World War II. In July 1945, with the war with Germany won, USS O-2 was decommissioned. She was sold in November of that year.
