Or behind the aft pressure bulkhead, of up above the nose gear well under the cockpit, or under the passenger compartment where the wings meet, or other such confined spaces. I would sometimes spend entire shifts inside those places, only coming out for lunch and to relieve myself. I guess I just got used to it.

I knew the wings were where the fuel was stored in many/most aircraft. I'd never thought about how big they are or if there was enough room with reinforcing ribs and whatnot to get inside one. I guess I wouldn't have thought there was that much room, but the overall size of a passenger's jet probably works to have our heads think "the wings aren't that big. I definitely wouldn't have expected to be able to get inside the vertical stabilizer, especially all of the way to the top. Cool!
