Humans cannot fly naturally because our bodies lack the biological adaptations required for powered flight. Flight demands a combination of low body mass, large wing surface area, powerful flight muscles, and lightweight skeletal structures. Birds, for example, have hollow bones, specialized chest muscles, and wings designed to generate both lift and thrust. Humans, on the other hand, have relatively dense bones, a body mass that is too great for arm-powered flight, and arms that are far too short and weak to function as effective wings. According to the principles of aerodynamics, an object must generate enough lift to overcome its weight, but the surface area of human arms is insufficient to produce the lift needed to keep a person airborne. Additionally, our muscles cannot generate the continuous power output required for sustained flight. While humans have overcome these biological limitations through technology such as airplanes, helicopters, and wingsuits, our natural anatomy makes independent flight impossible.
