Aeronautics

Aeronautics (from Greek ὰήρ āēr which means "air" and ναυτική nautikē which means "navigation, Airmanship", i.e. "navigation of the air") is the science involved with the study, design, and manufacturing of airflight-capable machines, or the techniques of operating aircraft and rocketry within the atmosphere. While the term—literally meaning "sailing the air"—originally referred solely to the science of operating the aircraft,it has since been expanded to include technology, business and other aspects related to aircraft.
