I built a 6 inch wing span model of the first aircraft shown carved from very light weight balsa some 15yrs ago, it flew so well I won a local indoor flight competition for gliders and for oldest. lol
Quote from site " In 1898, a peculiar six-inch wooden object was found in a tomb at Saqquara, Egypt that dated back to about 200 BCE. The object had a body or fuselage, seven-inch wings that curved downward slightly, a fixed rudder, and a tail. It looked very much like a modern airplane or glider. But, since airplanes had not yet been invented in 1898 (never mind ancient Egypt), it was labeled as a model of a bird and stored away in the basement of the Cairo museum.
The object was rediscovered many years later by Dr. Khalil Messiha, an authority on ancient models. According to Messiha and others who have studied the object, it has characteristics of very advanced aerodynamics, much like modern pusher-gliders that require very little power to stay aloft. The curved wings are today known as reverse dihedral wings, which can attain great amounts of lift. A similar design is employed on the supersonic Concorde aircraft.
Was this just a child's toy? Or was it a scale model of an aircraft the Egyptians planned to build... or did build? If they did build a full-scale version of the aircraft, no evidence exists for it. No full-size airplanes have been found in any pharaoh's tomb to fly him to the land of the dead."
