Across the Wasteland, there were rumors of random books and pages detailing flying machines, and one in particular was called the "Flying Fortress."
Among the marketplace debates, Jack Slade, the defacto criminal leader of the Nomadic Towns, asserted his own position that there were absolutely no such things as flying machines. He said the priests must have made a mistake in translating those stories, and that, in fact, "Flying" should have been translated to "Driving."
To further prove his point, Slade had his personal mechanics build a fully functional "Driving Fortress."
Now, Jack Slade and his gang rumble across the northern plains in his Driving Fortress, bristling with guns, strengthening his influence over the Nomadic Towns and defying the edicts of the Oak Street Church.
This beast will need some planning, because, to allow the machine guns to traverse and the doors to open and close, I need to paint the interior before reassembling the car. Once the car is reassembled (with waist and forward gun in place), I can begin construction on the exterior, including a couple pieces of armor as well as the tail gun.
Once assembled, I plan on painting the whole thing as an aluminum shell. The trunk and fins will get a swath of color to help the chrome bumper contrast with the tail gun. Everything will get a regular coat of rust and dust. And, if I get ambitious enough, I might try to paint some pin-up art on the hood. Might.
