Carrier

Large passenger service vehicles, these usually have a cockpit crew of 3 (pilot and navigator up front, co-pilot in a separate cockpit round the back for better visibility when maneuvering) and can take up to a few hundred passengers. Unlike a shuttle, these will have engines somewhere around the midsection in order to make them more stable when accellerating. Unfortunately, this increase in stability necessitates 2 or 3 engines which are either bolted to opposite sides of the ship, or (especially in the case of hotter vapour pile) on wings or nacelles protruding from the sides.
