Aircraft/Missile Information
President Roosevelt used the Sacred Cow only once before his death in April 1945; however, the Sacred Cow remained in presidential service during the first 27 months of the Truman Administration. On July 26, 1947, President Truman signed the National Security Act of 1947 while on board the Sacred Cow. This act established the Air Force as an independent service, making the Sacred Cow the "birthplace" of the USAF.
