National Air and Space Museum is a must-go spot in Washington D.C. It is amazing to retrace how human learns flying like a bird and exploring the universe.
Human doesn't have wings. But we have metal bird (a nick of aeroplane in the past) as a tool carrying us in the sky.
Grand grad fathers of modern planes. Simple but handsome.
Only the very rich could afford air travel decades ago. Their valuable belongings were well kept in cloak room.
Fashionable old crew uniforms.
Various reasons of travelling.
This demonstration probably can serve as a preliminary test for cadet selection.
