Pemberton-Billing P.B.25
The Pemberton-Billing P.B.25 was a First World War British single-seat scout aircraft built by Pemberton-Billing Limited, later Supermarine Aviation Works Limited. Design and development The P.B.23 was designed in 1915 as a single-seat biplane scout, with a fuselage nacelle strut-mounted between the wings. The nacelle had an open cockpit for the pilot at the front and at the rear an 80 hp (60 kW) Le Rhône 9C engine driving a pusher propeller. Twin fins and rudders were mounted on a wide-span tailplane with an elevator attached, all connected to the wing structure with four tailbooms. The P.B.23 failed to gain an order after it first flew in September 1915, but twenty of an improved version, the P.B.25, were ordered by the Royal Naval Air Service. The P.B.25 had swept-back wings, a modified landing gear and a revised fuselage nacelle and although originally powered by a 110 hp (82 kW) Clerget rotary engine, the 20 RNAS aircraft were fitted with Gnome Mo ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organization ...

RNAS Hendon
The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty's Air Department, and existed formally from 1 July 1914 to 1 April 1918, when it was merged with the British Army's Royal Flying Corps to form the Royal Air Force (RAF), the world's first independent air force. It was replaced by the Fleet Air Arm, initially consisting of those RAF units that normally operated from ships, but emerging as a separate unit similar to the original RNAS by the time of World War 2. Background In 1908, the British Government recognised the military potential of aircraft. The Prime Minister, H. H. Asquith, approved the formation of an "Advisory Committee for Aeronautics" and an "Aerial Sub-Committee of the Committee of Imperial Defence". Both committees were composed of politicians, army officers and Royal Navy officers. On 21 July 1908 Captain Reginald Bacon, who was a member of the Aerial Navigation sub-committee, submitted to the First Sea ...
