B-17's were the heavy hitters over Europe in WWII. Their losses were some of the highest in WWII. Of the original 1200 pilots and crew, only about 300 survived. B-17's were known to take a lot of damage and still make it home. The photo of the B-17 with the exploded nose made it back to base. The skies were full of these monsters on regular thousand plane raids. Something that must have been unreal to witness... This gets into my head.
