Well there's also the possibility of entering through something that would connect to the interior of the ship from the outside that could be fairly easy to pry into like missile bays or something similar like that, assuming the [i]Lone Star[/i] has missile bays and that they can be reloaded from inside the ship.

You wouldn't really know those kinds of details about the ship unless someone was already intimate with the design, or could get their hands on a schematic of some kind.
