Kirby Radar Kite

"Almost all the Kirby Kites still flying at the outbreak of World War II were impressed into the Royal Air Force for use as training aircraft for assault glider pilots. Kirby Kites were also used, along with other types of glider, to assess the ability of the Chain Home radar system to detect aircraft largely constructed of wood. These tests carried out over the English Channel were successful in showing that even gliders with very little metallic content could be detected, though the strength of return depended on how much metal was on board. After use by the Glider Training Schools the surviving Kirby Kites were passed to the Air Training Corps. Seven complete Kirby Kites survive, plus another that had no wings. New wings have been built for this Kite."

The Boeing P-8 Poseidon (formerly Multimission Maritime Aircraft) is an American maritime patrol aircraft developed and produced by Boeing Defense, Space & Security, modified from the 737-800ERX. It was developed for the United States Navy (USN).

Boeing 247

Boeing 247

The Boeing Model 247 was an early United States airliner, considered the first such aircraft to fully incorporate advances such as all-metal (anodized aluminium) semimonocoque construction, a fully cantilevered wing and retractable landing gear. Other advanced features included control surface trim tabs, an autopilot and de-icing boots for the wings and tailplane.

"Ordered off the drawing board", the 247 first flew on February 8, 1933 and entered service later that year. Subsequently, development in airliner design saw engines and airframes becoming larger and four-engined designs emerged, but no significant changes to this basic formula appeared until cabin pressurization and high altitude cruise were introduced in 1940, with the first pressurized airliner, the Boeing 307 Stratoliner.
