Here is the ball turret which was very small in order to reduce
drag, and was operated by the shortest man of the crew. To enter
the turret, it was moved until the guns were pointed straight
down. The gunner placed his feet in the heel rests and then
crouched down into a fetal position and then put on a safety
strap, then he closed and locked the door. The gunner sat in the
turret with his back and head against the rear wall, his hips at
the bottom, and his legs held in mid-air by two footrests on the
front wall. This positioned the gunner with his eyes roughly
level with the .50 caliber machine guns, and located to either
side of the gunner. The cocking handles were located too close
to the gunner to be operated easily, so a cable was attached to
the handle through pulleys to a handle near the front of the
turret.
