No.11 Group was a part of which air force that emerged as the largest air force in the world in 1918?
Royal Air Force The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain.
Escadrille SPA.124 Escadrille SPA.124 of the French Air Service was established in February 1918. The members of the earlier "Escadrille N.124", more widely known as the Lafayette Escadrille, largely transferred into the United States Air Service on 18 February as the 103rd Aero Squadron. The remaining French personnel were formed into a unit operating "SPADs". In May 1918, the unit was dubbed the Escadrille Jeanne d'Arc to differentiate it from its famous predecessor.
