Magnificent photo of the Flying Fortress’ classic tail turret. This “alive” turret belong to the very airworthy B-17G “Nine O Nine”. Such a gorgeous “casemate” shape and equipped with its definitely dated old ring and head sight…, just plain glorious. This cramped and firing angle-limited turret was replaced in later G-models by the “Cheyenne” tail turret -developed by the United Air Lines’ modification center at Cheyenne, Wyoming. A more modern design: with wider firing angles, reflector sight, roomier, confortable…..and definitely a lot less cooler.
