Wright Brothers and Santos Dumont

The video explores the debate over who invented the first flight, focusing on the Wright Brothers and Sanders Duman. It discusses the criteria for a successful flight, including powered takeoff and human carriage. The Wright Brothers' flight is analyzed, noting their reliance on external aids like headwinds and catapults. In contrast, Sanders Duman's design, the 14 B, is highlighted for its innovative features like the dihal angle, which provided stability without external aid. The video concludes by advocating for Duman's recognition in history alongside the Wright Brothers.
