A civilian shuttle was a type of commercial or private shuttlecraft used for a variety of purposes.
Blue Star Line shuttlesEdit
In the 2260s, the Blue Star Line company owned and maintained hundreds of shuttles. Their standard low occupancy, long-range civilian shuttle was a rather common sight in some parts of Federation space. In 2269, Spock rented shuttle RD-178 from the Blue Star Line office in the Rigel star system. A class F shuttlecraft designated TRN-148 was in the same hangar when Spock departed.
