U.S. Air Force Capt. Charles B. DeBellevue (Weapons Systems Officer) flying with his pilot, Capt. John A. Madden, in a McDonnell Douglas F-4D, shoots down two MiG-19s near Hanoi. These were Captain DeBellevue’s fifth and sixth victories, which made him the leading American ace (an unofficial designation awarded for having downed at least five enemy aircraft in air-to-air combat) of the war. All of his victories came in a four-month period. Captain Madden would record a third MiG kill two months later.
