Chuck Yeager & Walter C. Williams dual-autographed aviation commemorative cover celebrating the 25th anniversary of the Bell X-1A’s first powered flight, postmarked February 21, 1978, Edwards Air Force Base, California. Brigadier General Chuck Yeager, legendary test pilot and first person to break the sound barrier, inscribed: “I chased Skip on this flt in an F-86D – Charles E. Yeager, Brig Gen USAF Ret.” Walter C. Williams, Chief of the NACA High-Speed Flight Station, has also signed boldly at right. The Bell X-1A program represented a major milestone in supersonic research, and this cover connects two of the most important figures in America’s high-speed flight history.
