Although Charles Sullivan was not a regular member of the crew, on 20 July 1944 he was serving as the acting Flight Enngineer on a B-17 (42-31812) that was nicknamed Destiny’s Child. Destiny Child's mission that day was to bomb the Mockau Airfield near Liepzig in Germany.  As they came close to the target, the tail gunner spotted German F-109s coming up to attack them from the rear.  The fighters hit one of Destiny’s Child’s engines, damaged its wings, and set the plane on fire.  The pilot gave the order to bailout, and five of the crewmembers were able to do so.  However, the other four, including Charles, were still on board when the plane went into a spin and exploded in mid-air near Chemnitz.  Destiny Child’s pilot, Charles Van Ausdall, and its tail gunner, Vernon Winters are also buried at the Ardennes American Cemetery.
