Using this passive ability can the workers move from the hex of the airship to a tunnel exit or only from a mine/tunnel to the airship? We decided that the airships functions as entry or exit to the tunnel system. Is that right?
Marco: I'm sorry about the slow answer--I've been at a convention today. Using the Drill ability, you'll act as if the airship's territory is a Mine for all worker movement. So you can move from it to a tunnel or your mine, or from your tunnel or mine to it.
