human flight

Human flight is achieved through the use of aircraft like airplanes and helicopters, which generate lift by moving air faster over their wings or rotor blades. This creates a pressure difference that lifts the craft into the air. Airplanes primarily rely on engines for forward thrust, allowing wings to produce lift, while helicopters use rotating blades to achieve vertical takeoff and landing. These principles are based on aerodynamics, where the shape of wings and blades control airflow and generate the necessary force to overcome gravity and enable controlled flight.
