The Ryan Firebee was a series of target drones or unmanned aerial vehicles 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.

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 (481 kg) of thrust. The Air Force then obtained small numbers of a Q-2B with a more powerful engine for high-altitude performance.

William Tell (in the four languages of Switzerland: German: Wilhelm Tell; French: Guillaume Tell; Italian: Guglielmo Tell; Romansh: Guglielm Tell) is a folk hero of Switzerland. His legend is recorded in a late 15th-century Swiss chronicle.

It is set in the period of the original foundation of the Old Swiss Confederacy in the early 14th century. According to the legend, Tell — an expert marksman with the crossbow — assassinated Gessler, a tyrannical reeve of Habsburg Austria positioned in Altdorf, Uri.

Along with Arnold Winkelried, Tell is a central figure in Swiss patriotism as it was constructed during the Restoration of the Confederacy after the Napoleonic era.

There are several accounts of the Tell legend. The earliest sources give an account of the apple-shot, Tell's escape and the ensuing rebellion. The assassination of Gessler is not mentioned in the Tellenlied, but is already present in the White Book of Sarnen account.

The legend as told by Tschudi (ca. 1570) goes as follows: William Tell, who originally came from Bürglen, was known as a strong man and an expert shot with the crossbow. In his time, the Habsburg emperors of Austria were seeking to dominate Uri. Albrecht (or Hermann) Gessler, the newly appointed Austrian Vogt of Altdorf, raised a pole in the village's central square, hung his hat on top of it, and demanded that all the townsfolk bow before the hat. On 18 November 1307, Tell visited Altdorf with his young son and passed by the hat, publicly refusing to bow to it, and so was arrested. Gessler — intrigued by Tell's famed marksmanship, yet resentful of his defiance — devised a cruel punishment: Tell and his son would be executed, but he could redeem his life by shooting an apple off the head of his son, Walter, in a single attempt. Tell split the apple with a bolt from his crossbow.
