What kind of airplanes were used during World War I?

Question:Old ones.

Sorry, had to be a smartass. It was in the infancy of flight, so there were huge advances during the war. Biplanes were the norm, things like Spads, Sopwith Camels, Fokker D-7s. There were a few monoplanes developed late in the war, and tri-planes were also used. In the early part of the war, planes didn't even have mounted machine guns. The ability to synch up the engine with a gun so the pilot could sight and fire a front mounted gun without shooting off his propeller was a huge advance.

The basic mission was to strafe enemy ground forces, but dog-fighting became an integral part in order to protect their ground forces from attack.

Bombers became a new part of the inventory during the war also, starting with a co-pilot just dropping grenades or light ordnance from the plane to an actual mounted bomb. All planes in this era were made of wood and cloth and were extremely vulnerable to ground fire, even from standard infantry weapons. The Red Baron was shot down from the ground with a simple machine gun.

Biplanes. That is, they had two sets of wings, one over the other. The planes were made out of wood and canvas, which made them quite light (and fragile). They were also very slow, with top speeds of about 70 mph and a ceiling of about 5,000 ft. The cockpits were open to the weather.
