Information: - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. - A flying ace or fighter ace is a military aviator credited with shooting down several enemy aircraft during aerial combat. The actual number of aerial victories required to officially qualify as an "ace" has varied, but is usually considered to be five or more. The few aces among combat aviators have historically accounted for the majority of air-to-air victories in military history. - Commandant Air Cadets is the title given to the Royal Air Force officer who is responsible for running the Air Cadet Organisation, embracing the Air Training Corps (ATC) and the RAF Sections of the Combined Cadet Force (CCF RAF). The current Commandant Air Cadets is Air Commodore Dawn McCafferty. - Air commodore (abbreviated as Air Cdre in the RAF, IAF and PAF; AIRCDRE in the RNZAF and RAAF) is a one-star rank and the most junior general rank of the air-officer which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence such as Bangladesh, and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. The name of the rank is always the full phrase and is never shortened to Commodore, which is a rank in various naval forces. Air commodore is a one-star rank and the most junior air officer rank, being immediately senior to group captain and immediately subordinate to air vice-marshal. It has a NATO ranking code of OF-6 and is equivalent to a commodore in the Royal Navy or a brigadier in the British Army or the Royal Marines. Unlike these two ranks, however, it has always been a substantive rank. Additionally, air commodores have always been considered to be air officers whilst Royal Navy commodores have not since the Napoleonic Wars been classified as officers of flag rank, and British Army brigadiers have not been considered to be general officers since 1922 when they ceased to be titled as brigadier-generals. In other NATO forces, such as the United States Armed Forces and the Canadian Armed Forces, the equivalent one-star rank is brigadier general. - The Air Training Corps (ATC) is a British youth organisation sponsored by the Ministry of Defence and the Royal Air Force. A Full Time Reserve Service RAF officer serves as Commandant Air Cadets at the rank of Air Commodore. The majority of staff are volunteers although some are paid for full-time work. Although many ATC cadets go on to join the RAF or other services, the ATC is no longer set up as a recruiting organisation. - 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. - Lieutenant John Arthur Aldridge MBE was a First World War flying ace credited with five aerial victories .
