It can be argued that the B-17 was the one that brought Nazi Germany down to its knees. Day and night, it struck deep into enemy territory mostly unescorted, laying to waste the industrial might of Hitler and his capacity to sustain the war. It dropped almost half of the 1.5 tons of bombs used in Europe. This strategic bomber carried a crew of ten and bristled with 50 cal. machineguns that made it a formidable opponent of the Luftwaffe’s fighters. With its high-altitude bombing run, it put the plane out of reach of most anti-aircraft fire thus making it almost invulnerable from flak, hence the nickname. I shot “Sentimental Journey”, one of the few remaining flying combat bombers parked on the tarmac at the Arizona Commemorative Air Force Base in Tucson.
