Francis and Gertrude Rogallo have saved and stored a large number of items that were used in various experimental developments of the flexible wing concept. Following the invention and patenting of the wing, the Federal government expressed interest in the concept. Rogallo was involved in a number of government projects in which the flexible wing served as the basis for experiments in powered and unpowered aircraft, landing cargo and vehicles, and returning spacecraft to earth. A wealth of artifacts accumulated over the years of personal and governmental experiments could, if catalogued and readily available for study, serve historians, experimenters, engineers, and enthusiasts. The Rogallo flexible wing has had an enormous influence on low speed aviation. What further breakthroughs await humanity in this realm of flight resulting from the evaluation and study of these artifacts? The Rogallo Foundation, through its membership and gift programs, can help you express your interest in preserving, protecting, cataloguing, and researching these priceless artifacts.
