Two Air Force crews complete the first trans-Pacific helicopter flight as they land their Sikorsky HH-53Cs at Da Nang Air Base, South Vietnam, after a 9,000-mile flight from Eglin Air Force Base, Fla. The helicopters were refueled in flight.
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.
