Moon shuttle

From Memory Alpha, the free Star Trek reference.

A moon shuttle was an unsophisticated type of shuttlecraft which were used during the 22nd and 23rd centuries.

In 2155 of the mirror universe, Captain Jonathan Archer imagined that he saw a counterpart of himself from a parallel universe. The illusion told him that he would more probably "end up commanding a moon shuttle" than receive official authorization from Starfleet to command an advanced starship named the Defiant.

Aboard the USS Enterprise of our universe, 111 years later, Doctor Leonard McCoy was berated by Captain James T. Kirk for not alerting the captain on the ship's red alert status during a physical. The doctor then quipped "What am I, a doctor or a moon shuttle conductor?" (TOS: "The Corbomite Maneuver")
