Explanation
If you have a passion for airplanes and other aircraft, you might be destined for a career in aeronautics, which is the study and design of flying machines within the atmosphere. Whether your interest lies in building aircraft or flying planes, you can describe your area of interest as aeronautics. The term aviation can also be used, although it typically doesn't include airships or dirigibles, like blimps and zeppelins. The word aeronautics literally means "sailing the air," from the Greek roots aero, "air," and nautikē, "navigation."
