Pressure Pirates
this was the term used to describe any gang of pirates who preyed upon starships and orbital stations which worked in the atmosphere of gas giant planets. They disabled their targets, causing the craft to sink into the atmosphere. As soon as the ships were evacuated and left to fall into the planet's core, the pressure pirates moved in. Using specially-designed equipment that could withstand intense pressure, the pirates then tracked the ship as it sank and looted it for any profit they could find.
