A regimented squadron by 1914 standards, but the Dorand Do1 seems to have served in very small numbers. Designed as a reconnaissance bomber with armour plates weighing 90 kg around the cockpits, the type was badly underpowered but saw some action early in the Great War. It was redesigned as the Dorand AR. Dijon - Longvic was an airbase for 102 years, from 1914 until 2016. Photo from: Bibliothèque nationale de France - Gallica
