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.
One of General Atomics Aeronautical Systems’ prototype Collaborative Combat Aircraft drones crashed shortly after takeoff April 6, and the company has paused its test flights while it investigates the incident.
