Terminology-wise, "aeroplane" is more scientific in its prefix. The term "hydroplane", for example, describes a similar effect of lift on water; the term "waterplane" sounds stupid in a way. In fact though, a lot of nautical terms (since "nautical" has its roots as a sailing term, astronaut means "sailor of stars") come from sailing; when you think about it, automobiles and cars were at one time just referred to as horseless carriages. The names of vehicles either come from the eccentric naming of the inventor, a scientific concept, or a reworking of the name of a previous technology.
