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.
List of Royal Flying Corps generals The following is a list of senior Royal Flying Corps generals. While officially general officers are not considered to belong to any regiment or corps (simply being "late" of their erstwhile regiment), in practice almost all the general officers to hold a Royal Flying Corps-related appointment gained their promotion to the general officer ranks in that appointment and remained in such appointments until the creation of the Royal Air Force on 1 April 1918. Royal Flying Corps generals then became Royal Air Force generals.
