Once upon a time, I got bored so I drew a few flying things.
From up > down, left row:
1. A large orange cruise skyship, used for flying long distances over long periods of time. Average passenger number.
2. A small red delivery skyship, commonly used to deliver a small amount of supplies or equipment across short distances, usually islands. Can also be used as a 2-3 passenger leisure vehicle (think; hot air balloon).
3. A small blue nimble flyer, used as sport. Can fly at high speeds, fastest at 80-90 miles per hour. Carries 1 or 2 passengers only. Compare to a jet ski or speedboat.
4. I have no idea what this thing is, probably a glider and/or ornithopter thing.
5. A red-tinted airship, one of the most commonly used ones. Can be used for various purposes ranging from sport & leisure to emergencies & delivery. 15-25 passengers.
6.A small, lightweight, one-man hovercraft; used for exploration and mining in places where no other airships can go due to their size and relative bulkiness.
7. A large green skyship, comparable to the pirate and biologist ships of the 19th century. Used for deliveries, transporting people, exploration and occasionally warfare.
8. The largest and grandest of them all, a floating city. Supported by one large gas balloon divided into 50 smaller gas cells and 100 other smaller balloons around the city. Used as a portable mining base that can be transported by a system of fans and rudders powered primarily by captured solar energy. Maximum population: 12000 people.
