Chuck Yeager Breaks Sound Barrier Again as Postal Service Issues 'First Supersonic Flight' Stamp.EDWARDS, Calif.--(BUSINESS WIRE)--Oct. 14, 1997--The 50th anniversary of man's first successful flight through the sound barrier was celebrated Tuesday with the issuance of a new commemorative stamp A commemorative stamp is a postage stamp issued to honor or commemorate a place, event or person. Most postal services of the world issue several of these each year, often holding first day of issue ceremonies at locations connected with the subjects. here at the Air Force Flight Test Center. The First Supersonic Flight Supersonic flight Relative motion of a solid body and a gas at a velocity greater than that of sound propagation under the same conditions. The general characteristics of supersonic flight can be understood by considering the laws of propagation of a stamp will start appearing on envelopes, cards and letters tomorrow, Oct. 15, as 173 million self-adhesive, 32-cent stamps will be available at the nation's post offices. "The First Supersonic Flight stamp pays tribute to American Technological achievement and reminds us all that, throughout our nation's history, many barriers once thought impossible to break have been surpassed with a powerful combination of scientific know-how and human spirit," said Allen Kane, Postal Service postal service, arrangements made by a government for the transmission of letters, packages, and periodicals, and for related services.

To kick off today's 50th anniversary celebration, U.S. Air Force Brigadier General (ret.) Charles E. "Chuck" Yeager made in spectacular fashion what is believed to be his final military flight. He piloted an F-15 jet fighter Jet fighter may refer to:
Air-launched at an altitude of 23,000 feet from the bomb bay of a Boeing B-29, the X-1 used its rocket engine to climb to its test altitude during its 78 flights. To break the sound barrier (Mach 1), the X-1 reached a speed of 700 miles per hour (Mach 1.06) at an altitude of 43,000 feet. Many important structural and aerodynamic advances were first employed in the X-1, including extremely thin yet exceptionally strong wing sections and a horizontal stabilizer Noun 1. horizontal stabilizer - the horizontal airfoil of an aircraft's tail assembly that is fixed and to which the elevator is hinged horizontal stabiliser, tailplane that could be adjusted up and down to improve control, especially at transonic transonic in ultrasonography, the complete transmission of sound so the image appears black; anechoic; echolucent. (near the speed of sound) speeds. Because of the stabilizer's success, later transonic military aircraft were designed with all moving horizontal stabilizers as standard equipment. The X-1's fuselage was shaped like a .50 caliber bullet. Even the windscreen was specially faired to retain the bullet shape. Nevertheless, it carried more than 500 pounds of flight test instruments. On March 26, 1948, with Yeager back at the controls, the X-1 attained a speed of 957 miles per hour (Mach 1.45) at an altitude of 71,900 feet. This was the highest velocity and altitude reached by a manned airplane up to that time.

Its horizontal layout features a side view of the X-1 as it hits Mach 1, with the words "First Supersonic Flight 1947" in all capital letters across the top of the stamp. "USA 32" appears in the lower left-hand corner. The X-1 illustration was reviewed and approved for its authenticity by General Yeager. It includes the moniker (1) A name, title or alias. See alias.
