Yes, 12 .50 BMG caliber machine guns, to be exact. B-17G "I'll Be Around" in her very own hangar at the Pima Air and Space Museum in Tucson, Arizona. Don't ask me why my son looks depressed in the picture - he had the time of his life! Oh, yes about the guns...notice how well I represent CZ-USA?
Here's the part most people DON'T know - they are live and loaded with live ammo. The electrical firing circuits are disabled. The 309th Bombardment group wanted their plane to be as close to authentic as possible. Therefore the plane ostensibly belongs to the US Air Force, which allows the museum to keep the weapons live, locked and loaded. She is perfectly restored, and fully flight capable. They would have to replace the upper turret, seen to the right, back where the dummy turret is right now, drop the four dummy bombs and find some live ordnance. Imagine this plane finding cartel convoys...
In this picture, the man in the wheelchair was the navigator on a B-17 in Europe. The gentleman in the red hat was the co pilot of the very plane behind him, but in the 1950s as part of a CIA run.
