It has only been since July 25th, 1909, the day on which Louis Blériot has crossed the Channel, that the use aircrafts for military purposes was considered.
Nevertheless, in 1914 the observation assignments were traditionally assigned to the mobile light cavalry, but the use of new, automatic firearms made this task virtually impossible. Aviation, and especially pilots, became the eyes of the army. From that moment on, aviation keeps evolving itself unlimitedly as a weapon.
During the war many new things were invented or improved. Among these the speed of the aircrafts, the distance they could fly, the load that could be taken along. Not to mention that observation through photography allowed to make more detailed maps, the fire power improved, the dogfights became more intense and the bombardments became heavier.
Unfortunately, war remains a powerful motor for ‘the evolution of men’.
