| | SPACE.com -- Higher & Faster: Memorial Fund Established for X-15 pilot Joseph A. Walker |
 | | Walker went on to fly the X-15 to an unofficial speed record of 4,104 mph on June 27, 1962, and on August 22, 1963, reached an unofficial altitude record of 354,200 feet, proving once again that a winged-aircraft could be flown into space and landed safely. |
 | | Joe Walker was born February 20, 1921, and raised on a farm in Washington, Pennsylvania. |
 | | Walker worked to develop the reaction control system (RCS) used to adjust the attitude of the X-15 while in the upper portion of the atmosphere where the dynamic pressure is so low that conventional flight controls such as flaps, ailerons, or speed brakes are useless. |
