October must be the month during which we celebrate Charles Chuck Yeager’s historic achievement of breaking the sound barrier in level flight on October 14 ,1947. Air Corps Captain Yeager took the Bell X1 rocket plane beyond buffeting transonic phenomena, he became the first to create a sonic boom over Muroc Army Airfield, nowadays Edwards AFB in California. For the first time supersonic flight, at Mach 1.06 (807 Mph or 1300 km/h) was recorded as Yeager remained supersonic for 20 seconds before shutting down the engines. By October 1947, the Air Force became a separate military service.
