Commemorative tribute banner honoring U.S. Marine Corps aviators Capt. Gary L. Bain and 1st Lt. William C. Ryan, Jr., who flew F-4 Phantom II combat missions together as a radar intercept team (call sign 'Boomslang') with Marine Fighter Attack Squadrons VMFA-323 and VMFA-115 from Marine Corps Air Station Chu Lai, South Vietnam, 1968-1969. The collage documents squadron life, flight operations, and camaraderie, and memorializes Lt. Ryan, killed in action on 11 May 1969, the same mission in which Bain was wounded and medically evacuated to the U.S. Naval Hospital in Pensacola, Florida. Project: 219920
