W. O. Holden writes to Senator A. S. "Mike" Monroney in support of the Sonic Boom Studies being conducted in Oklahoma City by the FAA, NASA, and the U.S. Air Force. Holden believes that continuing these tests is important for the state and the nation, and that Oklahoma City is the logical choice for the location due to the presence of the FAA Aeronautical Center. Holden believes that the successful completion of these tests will contribute to making 1964 a successful year for Oklahoma.
