Decks and Crew

These huge machines have up to seven decks stacked under the flight deck and a massive superstructure. to boot. This is required to house a crew of around 5000 technicians, pilots and sailors.

Gigantic lifts bring aircraft to and from the flight deck from hangars. Belowdecks, you'll find workshops, mess halls, crew quarters (which can be extremely cramped) and everything else needed to keep this mini-city afloat and operationally ready.
