The Early History of the Airplane

Two brothers trace their lifelong pursuit of heavier-than-air flight, describing early experiments, study of prior investigators, and the three central engineering problems: sustaining lift, producing power, and achieving controllable balance and steering. They explain why they rejected passive dihedral stability and developed deliberately neutral wing forms combined with active controls, notably wing-warping and adjustable rudders, and they detail iterative kite and glider trials used to test these ideas. The account blends technical explanation, practical trial-and-error, and reflection on contemporaneous successes and failures to show how control systems, rather than brute power alone, shaped their approach toward powered flight.
