Technical Sergeant Charles G. Jack distinguished himself by gallantry in connection with military operations against an opposing armed force near Tchepone, Laos, on 13 March 1971. On that date, Sergeant Jack was the Flight Engineer of an HH-53 Rescue Helicopter that twice attempted the rescue of a wounded United States Navy pilot from certain death or capture by hostile armed forces. With full knowledge of the extent of hostile fire in the area, and with complete disregard for his own personal safety, Sergeant Jack twice exposed himself unarmed in an open doorway of the helicopter to direct the pilot’s hover and operate the hoist, until withering ground fire crippled the helicopter and wounded two crew members, making continued rescue attempts impossible. By his gallantry and devotion to duty, Sergeant Jack has reflected great credit upon himself and the United States Air Force.
