Space Passenger and Freight Authority

The Space Passenger and Freight Authority, commonly referred to as SPFA, is global group of governments bodies in their respective planets. If that planet has achieved planetary transport, it has an option to join the SPFA and build fleets of ships. It handles passenger and freight space travel within ZACK.

It's main purpose is to justify and allow the usage characters from other universes, such as Z's friends, to co-exist by means of interstellar planetary transport, but also allows to grow in his own universe. These universes are treated as solar systems for simplicity. However, it cannot be used to travel between Z's own alternative universe, such as the 2005 FBDJ, which retroactively exists.

Ships
In ZACK, SPFA fleet of ships range from short- to long-range and vary in size. Shorter range ships are considered local and head to solar systems within relative range to it's main hub. These ships will often make planetary landings. Long-range ships are much more larger, often considered express, and make fewer stops in favor of longer distances. Furville is the only known SPFA hub, though more do exist.

Alternative universes
In the 2005 FBDJ, SPFA retroactively exists. SPFA's fleet consists of small, yet large, number of ships that handle varies short and long routes, as oppose to size based on the route's length. All ships are designed around the same height and dimensions of a human, since all species at that time followed this law, with the exception of two ships dragons for dragons or larger that can't land on planets.

Solar Systems
A canon's universe are treated and seen as solar systems within overall galaxy. This makes it more plausible to jump between different planets, as oppose to per-galaxy biases. Canons with a defined galaxy use a different space transport method under SPFA subsidiary.
