Hangar 1

From Memory Alpha, the free Star Trek reference

Hangar 1 was an active Starfleet facility in San Francisco in the 2250's. Located near the Starfleet Academy, Hangar 1 was used for the storage and maintenance of shuttlecraft. This hangar has a room dedicated for the medical evaluation and treatment of hangar personnel. In 2258, shuttles from the starship USS Enterprise were housed in this hangar. The Gilliam, the Moore, the Dimassa 01, and the unnamed Shuttle 2 were among the many shuttles found in this hangar.

That year, following a distress call from the Vulcan High Command, cadets were ordered to assemble in the hangar for assignment. The cadets received their assignments here, divided by ship according to their individual aptitude, and the cadets assigned to the Enterprise—those with the highest academic standing—embarked upon the shuttles and were ferried to the orbiting starship. Cadets assigned to other ships were rerouted to other hangars, or to transporters. (Star Trek)
