to 400 metres (980 to 1,310 ft) with a flying machine. === 19th century === Balloon jumping replaced tower jumping, also demonstrating with typically fatal results that man-power and flapping wings were useless in achieving flight. At the same time scientific study of heavier-than-air flight began in earnest. In 1801, the French officer André Guillaume Resnier de Goué managed a 300-metre glide by starting from the top of the city walls of Angoulême and he broke one leg on arrival. In 1837, French mathematician and brigadier general Isidore Didion stated, "Aviation will be successful only if one finds an engine whose ratio with the weight of the device to be supported will be larger than current steam machines or the strength developed by humans or most of the animals". ==== George Cayley and the first modern aircraft ==== George Cayley was first called the "father of the aeroplane" in 1846. During the last years of the 18th century, he had begun the first rigorous study of the physics of flight and would later design the first modern heavier-than-air craft. Among his many achievements, his most important contributions to aeronautics include: Clarifying our ideas and laying down the principles of heavier-than-air flight. Reaching a scientific understanding of the principles of bird flight. Scientific aerodynamic experiments were conducted to demonstrate drag and streamlining, movement of the center of pressure, and the increase in lift from curving the wing surface. Defining the modern aeroplane configuration comprising a fixed-wing, fuselage and tail assembly. Demonstrations of manned, gliding flight. Identified that a lightweight, powerful engine would be necessary for sustained heavier-than-air flight, now known as the power-to-weight ratio Recognized for establishing the theoretical foundation for engine use in airplanes and modern aircraft design by identifying and explaining the four fundamental forces of flight: lift, thrust, drag, and weight. Cayley's research on the aeroplane aimed to address the four fundamental areas that are essential to aeronautics: propulsion, structural design, aerodynamics, and stability and control. His work laid the groundwork for a comprehensive understanding of these critical components, which continue to be vital in the field today. Cayley's first innovation was to study the basic science of lift by adopting the whirling arm test rig for use in aircraft research and using simple aerodynamic models on the arm, rather than attempting to fly a model of a complete design. In 1799, he set down the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. In 1804, Cayley constructed a model glider, which was the first modern heavier-than-air flying machine. It had the layout of a conventional modern aircraft, with an inclined wing towards the front and an adjustable tail at the back with both tailplane and fin. A movable weight allowed adjustment of the model's centre of gravity. In 1809, goaded by the farcical antics of his contemporaries, he began the publication of a landmark three-part treatise titled "On Aerial Navigation" (1809–1810). In it he wrote the first
