Made long ago by the brotherhood of steel, great but crudely made airships were constructed and sent out over Chicago for an expedition that tragically went wrong, the airships were hit by a great storm and with many already lost, the remainder of the fleet crashed outside of chicago, forming a new chapter of the Brotherhood of Steel in Chicago from the ruins of the airships that weren't too badly damaged. This is a great build for those who like portable homes and air structures, with room in the interior to build and modify, I do hope you like it!
