That is what I worked on the first five years of my service. Stationed at Barksdale AFB, 2nd Bomb Wing.
I worked on the navigation systems for KC-135 and B52-Gs, which by the way, is what that one in the photo is. Awesome photos...... For anyone that does not know. That airman running the fuel boom is laying on his stomach on what looks like a weight bench. He is looking out a little window. That is where those photos were taken.
