A grouping of embroidered squadron patches associated with U.S. Air Force A-1 Skyraider ('SPAD') night-strike squadrons, known as 'Zorros,' that flew combat and interdiction missions over the Ho Chi Minh Trail during the Vietnam War. These patches commemorate mission milestones and squadron identity for aircrew flying the propeller-driven A-1H in a war increasingly dominated by jets. Project: 219092
