Insert Boy Here - being a tailgunner

Here is what the tailgunner's compartment looked like. 

The tailgunner on a bomber plane was popularly referred to as 'Tail End Charlie'. The tailgunner's compartment was at the very back of the plane. His job was to shoot down enemy aircraft, and to alert the pilot of any planes approaching from the rear. The tailgunner's exposed position made it the most dangerous job on a bomber plane. Many aircraft would return to base intact, except that the  tailgunner's compartment would be completely shorn off.
