Personnel shuttle
Personnel shuttles were specialized shuttle used by Starfleet to transport large numbers of personnel from one location to another.
Following the 2366 discovery of a previously unknown Human colony on Tau Cygna V, which consisted of a population of 15,253, USS Enterprise-D Captain Jean-Luc Picard contacted Starfleet to arrange transport for the colonists, who otherwise faced eradication by the Sheliak. Starfleet's chagrined response to Picard's request was that it would take three weeks for the arrival of a colony transport ship, equipped with dedicated personnel shuttles, to arrive for the assist.
Seeking an alternative, as the transporters aboard the Enterprise were unable to transport through the planet's atmosphere, was to load all of the Enterprise shuttlecraft to capacity with colonists, creating a feat that would take four weeks and four days to complete. (TNG: "The Ensigns of Command")
