That's where the ball turret gunner lives.
I thought the stories of the fun and frolics amongst the frozen food on Gulf Air were well known.
btw, I hate it when someone asks a question and we all censor ourselves for reasons of "security". I'm not saying it's the wrong reaction, but, how did we learn all the stuff we learned?
So I'll answer in the form of a question...
(1) Pressurisation? - what shape is the easiest to hold and maintain pressure, a D or an O?
(2) Do they stay there? - If they did, how would they effect egress (and ingress I suppose)?
(3) Which aircraft has, in common with Charring Cross Staion, the toilets downstairs?
