The Zeppelin fits through the same doorway size as a Pteranodon (single doorframe), so you can easily fly into your base without large gates or dino doors! (As of version 75.18)

Very slow, very fun. We can now all be sky pirates! Great early to mid game tool. Counts as a wood structure as far as damage goes but has a decent health pool. 1800 carry weight so limit yourself accordingly.

Not worth the resources. Doesn’t carry much at all, and is so slow. Save your polymer and other resources for other things.
