Flexible Flyer ad from the early 1900s. Samuel Leeds Allen patented the Flexible Flyer in 1889 [2] in Cinnaminson, New Jersey using local children and adults to test prototypes. [3] Allen's company flourished by selling these speedy and yet controllable sleds at a time when others were still producing toboggans and "gooseneck" sleds. [4]
Samuel Leeds Allen (May 5, 1841 – March 28, 1918) was the founder of S.L. Allen & Company in Philadelphia. He was the inventor of, and his company manufactured, both the Flexible Flyer sled and Planet Jr farm and garden equipment.
The Wright Flyer III is the third powered aircraft by the Wright Brothers, built during the winter of 1904–05. Orville Wright made the first flight with it on June 23, 1905 . The Wright Flyer III had an airframe of spruce construction with a wing camber of 1-in-20 as used in 1903 , rather than the less effective 1-in-25 used in 1904 .
English: Front in-flight view of Wright Flyer III during its 46th flight (which was the last photographed flight of 1905); Huffman Prairie, Dayton, Ohio, October 4, 1905.

Wright Flyer III piloted by Orville Wright over Huffman Prairie, 4 October 1905. The Wright brothers' flights in 1903 with their Flyer I are recognized by the Fédération Aéronautique Internationale (FAI), the standard setting and record-keeping body for aeronautics, as "the first sustained and controlled heavier-than-air powered flight".

Sleds with a greater surface area (anything but runner sleds) are able to make the first runs a great deal easier than the variety of sleds with metal runners. Runner sleds are typically faster once the snow has compacted or turned icy. In the 1880s, Samuel Leeds Allen invented the first steerable runner sled, the Flexible Flyer. Since that ...
In aeronautics, a flexible wing is an airfoil or aircraft wing which can deform in flight. Early pioneer aeroplanes such as the Wright flyer used the flexible characteristics of lightweight construction to control flight through wing warping. Others made collapsible wings for folding away, such as the flying car designs by Gustave Whitehead.
Roadmaster acquired Flexible Flyer Company, whose history dates back to 1889. In 1997 the Roadmaster bicycle division was sold to the Brunswick Corporation . [ 5 ] However, it had already become evident that production of low-cost, mass-market bicycles in the United States was no longer viable in the face of intense foreign competition, [ 6 ...
