The craft was uncontrollable, which Maxim, it is presumed, realized, because he subsequently abandoned work on it.

In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.

The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research.

Fighter aces appeared; the greatest (by number of Aerial Combat victories) was Manfred von Richthofen.

Following WWI, aircraft technology continued to develop.

Alcock and Brown crossed the Atlantic non-stop for the first time in 1919.

The first international commercial flights took place between the United States and Canada in 1919.

An early aircraft design that brought together the modern monoplane tractor configuration was the Blériot VIII design of 1908.

It had movable tail surfaces controlling both yaw and pitch, a form of roll control supplied either by wing warping or by ailerons and controlled by its pilot with a joystick and rudder bar. 1, was finished in 1909, and was test flown on June 17, 1910.

Other aviators who made similar flights at that time were Otto Lilienthal, Percy Pilcher, and Octave Chanute.

Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34 meter) wingspan that was powered by two 360-horsepower (270 k W) steam engines driving two propellers.

The engine weighed no more than 4 kg/k W (7 pounds per horsepower). By 1905, the Wright Flyer III was capable of fully controllable, stable flight for substantial periods.
