NASA's Armstrong Flight Research Center engineers in Edwards, California, are working on an increasingly complex aircraft called the Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D.
NASA has provided a report and files that contain geometry in an effort to allow others to build and analyze this aircraft design!

The first model aviation club was formed in 1908.. by a woman! Ms. Todd, from her childhood, was always interested in how things worked. She would disassemble toys, typewriters, and was once even scolded for using her mother’s scissors to cut wire. This interest in tinkering led her to design and patent a type writer copy holder in 1896. By the turn of the century her interest turned to aviation, and she began to experiment with rubber-powered models and airships. In 1906 she displayed one of her aircraft at the Aero Club of America show, held in Grand Central Palace, New York.
