Team Member: Scott Yi Dennis Eric Flight has been the dream of humankind since they watched in awe as birds soared effortlessly through the sky. But, according to accepted history, it wasnt until the 1780s that two Frenchmen achieved lighter-than-air flight when they were lifted into the air in a hot air balloon near Paris. Then powered, heavier-than-air flight became the goal. And although it was theorized that heavier-than-air flight was possible as early as the 13th century, and in the 16th century Leonardo da Vinci designed winged aircraft and a crude kind of helicopter, it wasnt until the Wright brothers made their first successful flights at Kitty Hawk in 1903 that powered flight became a reality. Thats the widely accepted history. Some researchers and a few rogue scientists believe theres evidence to suggest that humans achieved flight earlier in history - much earlier... so early, they say, that the knowledge of this technology has been lost and ancient stories that recount adventures of human flight have been relegated only to myth. Is it possible that humans developed the technology to fly in early civilizations - or in civilizations that are now lost to history? Lets take a look at what some call the evidence - intriguing artifacts, carvings, inscriptions and legends - that they say point to the true record human of flight. This object (shown in sketch) was found in 1898 in a tomb at Saqquara, Egypt and was later dated as having been created near 200 BCE. As airplanes were unknown in the days when it was found, it was thrown into a box marked wooden bird model and then stored in the basement of the Cairo museum. It was rediscovered by Dr. Khalil Messiha, who studied models made by ancients. The discovery was considered so important by the Egyptian government that a special committee of leading scientists was established to study the object.?? As a result of
