NIS AeroIndustries NA-235 Medium Range Transport seaplane
This description is heavily based on the EADS CASA CN-235 transport aircraft
The NIS AeroIndustries NA-235 Medium Range Transport seaplane is a multi-purpose, medium range transport aircraft designed for the rugged environment of Poseidon. It is a high-wing, twin turboprop seaplane with a fully pressurized and air-conditioned cabin. The rear cargo doors can be opened both in flight and while at rest on water.
This aircraft has been adopted by the GEO Patrol on Poseidon as its principal medium-range transport and patrol vehicle. It also serves as a mobile base of operations for when the GEO Patrol are in the field. For instance, it is deployed with the Longshore Crew.
