Looks like me just before starting a bomb run in AH, except it's a Romeo y Julieta instead of a cigarette, my computer desk doesn't look much like the nose of a bomber, and I'm older and fatter than that guy.
EDIT: It sounds like a bad idea to be smoking in a military aircraft packed with bombs, bullets and fuel 
Shouldn't be a problem except during refueling. Bombs and bullets are fine, and if there's fuel vapor in the crew compartment the plane has worse problems than someone smoking!
I read a book on Paul Tibbets a few years back and the author, making a point about how utterly unemotional Tibbets was about his work, told how Tibbets mentioned sitting directly over the bomb smoking his pipe while they were preparing it for takeoff. The author asked him if that didn't make him just a little nervous no matter how safe he rationally knew it to be, and Tibbets just didn't understand the question.
I'd get a bit of the heebie-jeebies just sitting on top of a nuclear weapon, let alone smoking there. I guess you get used to it.
