WW1 German Airship "Fliegendes Kanu"
(Fictional)
The WW1 German airship "Fliegendes Kanu" (Flying Canoe) was revolutionary for it's time. It had several advantages over ground tanks, such as being able to fly above most cannon fire while shooting at enemies down below.
The biggest disadvantage was the wind and how fragile the balloon was. Several iron plates were tied to the side of the balloon, but that didn't help much against gun fire.
It was designed so that 3-4 gunmen could shoot rifles through the little slits in the walls.
How to operate:
Set the throttle to max and use the small starter crank on the side of the engine down below. From there, you can tilt the engine down to provide downward thrust to start flying.
