The X-1, a joint effort of the Army Air Forces, NACA, and the Bell Aircraft Corporation, was built to get answers about flight in the transonic region (approaching and immediately surpassing the speed of sound) that researchers were unable to get through conventional ground and wind tunnel tests. Aircraft design had progressed rapidly during World War 11, but as high-performance fighters such as the Lockheed P-38 Lightning developed the capability of dive speeds approaching Mach 1, they began to encounter difficulties. Shock-wave, or "compressibility," effects could cause severe stability and control problems and had led to the inflight break-up of numerous aircraft. Many people began to <b>...</b>
