Advantages
- The biggest advantage of having an airship in the apocalypse is the zombies can't get you as you'll be high in the sky.
- Airships can stay afloat for weeks. This is another huge advantage because unlike planes or helicopters who have to land after a while, airships will remain afloat for a very long time.
- You can easily kill zombies from the sky. From an airship you can easily snipe down the undead or drop bombs onto them.
- Airships are very fuel efficient.
Disadvantages
- Airships are hard to find.
- If they are filled with hydrogen, then they are flammable and can catch of fire easily.
- They are fairly unstable and flimsy, so if there is a storm, they can crash easily.
