We’ve fantasized about flying high since the Stone Age. The 1903 Wright Flyer gave wings (and an engine) to that dream and allowed humans to mimic birds. Soon, we were working and reworking early biplane designs, creating modern flying machines that served both commercial and military purposes. With advancements in engineering, history has seen some strange aircraft concepts like ring-wing planes.
