AIRCRAFT

The airplane was just getting started in World War 1, therefore very new technology of the time. At the beginning of the war planes were used for surveying enemy territory and so pilots would report their findings of enemy movement so the aim of artillery guns could be adjusted to be more effective. Later planes were equipped for combat with other planes. They attached ground forces with machine guns and bombs, and also bombed submarines at the surface. Airplanes of World War 1 were mostly made of hard wood  (braced with steel wires), dipped in a flammable liquid to give them stiffness required to form a wing surface. One of the most famous pilots of World War 1 was the RED BARON, a German flying ace.
