Hot Air Balloons are non UDI-capable aircraft which spawn automatically around the State Fair. In SimCity 4, they do not serve a pratical purpose and exist purely for asthetic value. All of these airships have the same red blue and yellow design, and are manned by the same sims.
- There can only be a maximum of one hot air balloon spawned on the map at any given time.
- As with other aircraft (with the exception of landed aircraft), it is impossible to collide with a hot air balloon.
- The airship is never seen landing anywhere or taking off from any point.
