This booklet includes detailed drawings showing how to identify different aircraft. It starts with how to recognise German, Austrian and Turkish aeroplanes, all three allied during World War One. These countries’ planes should not be shot at. Foreign aeroplanes are then described, and these should be brought down. The German soldier is told to keep a clear head and above all not to shoot down his comrades by mistake. The booklet was for official use only.
Aeroplanes were a new and unknown military technology during World War One. It was only in 1910 that the first military aircrafts had entered service, in the French and German armies. Because of the unfamiliar technology and the speed of the aeroplanes it was not easy for the soldiers to recognise friend or foe. Booklets like this were created to help them. The brightly painted aeroplanes from the conflict, such as the Red Baron, are now internationally known icons of the war.
