Still, Wingspan industries is now fully functional. Will reside here while construction of underground lair begins. Decided to divide underground base into same 5 sectors. No single minion knows full layout and goings on.
Also, no constant traffic between underground, and above ground. Minions working in the lower levels stay there all day, and only after their shift go to the parking garage (also underground).
All minions and families reside at skyscraper nearby. Built by Johnson Construction in case of exactly this. Fully self-sufficient building. Recycling. Exception is food.
