Aircraft
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, and hot air balloons.
Airworthiness
Airworthiness is the measure of an aircraft's suitability for safe flight. Certification of airworthiness is conferred by a certificate of airworthiness from the state of aircraft registry national aviation authority, and is maintained by performing the required maintenance actions.
Aviation
Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as balloons and airships.
Safety
Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.

The saying ‘Getting there is half the fun’ became obsolete with the advent of commercial airlines.

Aviation
Ours is the commencement of a flying age, and I am happy to have popped into existence at a period so interesting.
Amelia Earhart, 20 Hrs 40 Mins (1928)
Safety
Now, it is true that the nature of society is to create, among its citizens, an illusion of safety; but it is also absolutely true that the safety is always necessarily an illusion. Artists are here to disturb the peace.
