During World War II, David Archibald and Paul Olson were on patrol together in separate fighter airplanes when they were attacked by a vastly superior force of enemy FW-190’s. Each of them became a U.S. Army Air Forces ACE-IN-A-DAY, credited with shooting down 5 enemy aircraft in aerial combat on December 18, 1944. Archibald’s badly damaged airplane subsequently crashed southeast of Cologne, and his unconscious body was pulled from the wreckage by German soldiers and taken prisoner.
