The KC-135, the first jet-powered tanker, makes its first flight. Numerous variants have been flown and the type has been used for everything from electronic surveillance to becoming an airborne laser laboratory.
Poor event planning and staffing contributed to a fatal mishap last April at Kadena Air Base, Japan, when rotor wash from an HH-60W helicopter knocked over a Japanese teacher from a Department of Defense Education Activity school attending a public aerial demonstration, according to an Air Force investigation.
