The Ryan Firebee was a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and one of the most widely used target drones ever built.

Ryan Firebee I
Q-2/KDA-1 Firebee
The Firebee I was the result of a 1948 US Air Force request and contract to Ryan for a jet-powered gunnery target. The first flight of the XQ-2 Firebee prototype took place in early 1951. The drone featured swept flight surfaces and a circular nose inlet. The initial models had distinctive "arrowhead" shaped end plates on the tailplane. The Firebee could be air-launched, specially modified Douglas A-26 Invader bombers being first used; or ground-launched with a single RATO booster.
Following successful evaluation, the target was ordered into production for the USAF as the Q-2A, powered by a Continental J69-T-19B turbojet engine, with 1,060 pounds-force (4.7kN) of thrust. The Air Force then obtained small numbers of a Q-2B with a more powerful engine for high-altitude performance.
Wu Zhen (simplified Chinese:吴镇; traditional Chinese:吳鎮; pinyin:Wú Zhèn) (1280-1354 C.E.) was a painter born in Jiaxing, Zhejiang Province, during the Yuan dynasty of China, one of the so-called Four Masters of the Yuan Dynasty. He followed the Dong Yuan school of painting. Following along with trends of the time, Wu's works tended less toward naturalism (i.e. painting exactly what the eye sees) and more toward abstraction, focusing on dynamic balance of elements, and personifying nature. His painting The Central Mountain, dated 1336, is perhaps his greatest work and shows his style very clearly. It is a symmetrical image, with one large mountain in its center and others to each side. The mountains have rounded tops, and in fact all of Wu's lines in this painting are smooth, curved and flowing. The painting is a reinterpretation of traditional landscape paintings as it brings abstract style and brushwork to landscape, primarily to create a work focused on balance.
