The B-17s

I really surprised myself with this film... and loved it. Ok, so it's got holes all OVER the place, wtf, Germany declare war and instantly it's Stalingrad... what the hell were those German tanks/haircuts, how the hell did they just waltz out of Stalingrad, how could they survive in the mountains...?? Eventually I saw a Mustang that had/hadn't/had/hadn't Normandy markings, but ffs... the B-17s... No Normandy markings and each and every one had identical fuselage and tail numbers and identical nose art on both the port and starboard sides. Come on lads, I get that some of it stretched the imagination, but that was just bloody laziness!
