They can also be acquired by killing or pickpocketing Old Lady Gibson or taking her key and using it on the metal box containing the thrust controls. With a Lockpick skill of 50 or higher, the lock on the box can be picked.
- There are two versions of the modules, with differing weights and values, though only the weightless and valueless one is used in the game in normal play. Both versions are marked as quest items.
- The thrust control modules have the same in-game model as scrap metal.
After completing the quest and obtaining the modules without getting them from Old Lady Gibson's metal box, you can obtain them again from the box and get another module, but since it is marked as a quest item, you will not be able to remove it from your inventory. [verified]
