It becomes a pain when you fall off a zeppelin in claims you are not trusted in and return to find that your aircraft is stuck until either someone gets on in that claim and gives you access. Or just in general getting down and up is annoying. To fix this, there should be a long ladder that sticks out of a "doorway" when you release your craft so you can get up and down. This also minimizes water towers.
You see... say I fell off and died. If I come back to it later the zeppelin is no longer piloted. /manoverboard will not help at all since you long finished piloting the craft. Or if you want to get down to a shop or something, you don't need to ask for perms to water bucket because the zeppelin hangs a ladder down.
