The navigators of the 97th Bomb Group B-17s checked their maps as they approached the Danube River from the north on the morning of June 23, 1944. So far they were on course and on time for their assigned target, the Romanian city of Giurgiu on the border with Bulgaria. The Italy-based Fifteenth Air Force had that day launched hundreds of bombers against targets affiliated with Ploesti and other Axis petroleum production and shipping points.
Nearly 70 miles south of Ploesti, the Flying Fortresses pressed through a thick anti-aircraft barrage. During the bombing run on Giurgiu, the B-17F Opissonya was struck by flak and began losing altitude, but pilot Lieutenant Edwin Anderson was determined to put his bombardier over the target.
Lieutenant David R. Kingsley crouched over the Norden bombsight in Opissonya’s nose, seeking the aim point. He ignored attacking Messerschmitt Me-109s and dropped his bombs through thickening flak. By then the B-17 had taken a beating: Anderson pulled off target with one engine out and serious airframe damage.
