Hi
There are fish concepts used in the aircraft industry. The Aero Space liner The Super Guppy B377-SG/SGT wide bodied cargo Aircraft was the successor to the Pregnant Guppy. Five Super Guppy's were made.
The Guppy (Poecilia Reticulata) is a Tropical Fish and is quite easy to keep, and they bred easily.
The concept of an aircraft drawing could be for several different reasons. It could be a simple work of art to showcase the aircraft, or a very detailed guide to understanding the parts and functions of the aircraft. It could explain how it functions, what it is made up of, how to repair certain parts.
The concept, I believe, is to transport people and goods by use of Air. This cuts out the traffic on roads, rail and water.
Do you mean used? Please be a little more specific, for example, What engines are used in aircraft, What instruments are used in aircraft.
A Cuttle Shuttle.
