And it was cold in a Flying Fortress, fifty below zero at high altitudes. In the picture, I’m standing by the waist guns. This particular B-17 is the G model, the last ones built, and it had plexiglass windows over the waist gun ports. Previous models had no plexiglass, and were even colder than the B-17G. Aircrews wore electrically heated suits, but frostbite was always a danger, although less of a danger than flak or fighters. I have known a couple of men who fought in B-17s, and they wouldn’t talk about what it was like up there.
