Balls of steel.
Reminds me of my bestie from High School. He joined the USAF right out of school. He got into the armaments maintenance portion at first. Decided he wanted to fly. Tail gunner on a B52. He loved it, "If we should happen to crash, tail gunner is most likely to survive." He was perty upset when the Buffs went to radar control on the mini guns, moved him to the middle of the plane with a radar screen in front of him.
Seems like his balls would be too big to fit in there.
