A patch that adds a coal-powered version of the airship.
If I can refine fuel, why use such a rudimentary vehicle?
This mod aims to let you dominate the skies before the industrial age. The research and construction costs are balanced to make it a manageable challenge.
The machinery in this version is considerably heavier, hindering its speed and capacity.
It also reduces the speed of the chemical version from 3 to 2 (it seemed too fast for an airship, a bit unbalanced).
