Designed and built by famed aircraft modeler Frank Ehling in the 1970s, these model airplanes are the smallest flying models in the National Air and Space Museum collection. They are powered by flies attached to the models with contact cement. Constructed from balsa wood and red tissue paper, the one-fly design has a wingspan of two inches, and the two-fly version, which features a delta-wing design, is four inches wide.
