From Wikipedia:
"
The Saqqara Bird is a bird-shaped artifact made of sycamore wood, discovered during the 1898 excavation of the Pa-di-Imen tomb in Saqqara, Egypt. It has been dated to approximately 200 BC and is now housed in the Egyptian Museum in Cairo. The Saqqara Bird has a wingspan of 7.2 inches and weighs 39.120 grams....


Controversial ideas
Some have suggested that the Saqqara Bird may represent evidence that knowledge of the principles of aviation existed many centuries before such are generally believed to have first been discovered.[citation needed]

Egyptian physician, archaeologist, parapsychologist and dowser[[2]] Khalil Messiha has speculated that the ancient Egyptians developed the first aircraft.[3] He wrote that it "represents a diminutive of an original monoplane still present in Saqqara."[3] He also claimed that the Saqqara Bird could function as a glider if it had a horizontal tailplane, which he "suppose[d] was lost,"[3] and noted that the Egyptians often placed miniaturized representations of their technology in their tombs.[4]

Messiha contended that the Saqqara Bird differs significantly from other statues and models of birds housed in the Cairo museum. According to Messiha, the Saqqara Bird has a vertical tailplane which is unlike the generally horizontal shape of a real bird's tail.[3] It is also legless and has wings set at an angle Messiha sees as similar to that of modern aircraft, which he considered an attempt to create aerodynamic lift.[3]

In spite of these claims, however, no ancient Egyptian aircraft have ever been found, nor has any other evidence suggesting their existence come to light. As a result, the theory that the Saqqara Bird is a model of a flying machine is not accepted by mainstream Egyptologists."
