means Any machine built to fly — planes, helicopters, gliders, airships — that stays up by moving through the air rather than floating free of it.

from A straightforward 19th-century compound of 'air' plus 'craft,' the same 'craft' that gives us watercraft — the old sense of 'craft' meaning a vessel or skilled construction, something built and steered rather than merely thrown. It surfaced once powered and lighter-than-air flight became real enough to need naming, borrowing the nautical logic wholesale: if a boat is a craft that moves through water, a flying machine is a craft that moves through air.
