flight in Eole, an uncontrolled hop that ends in a crash. Ader later will experiment with an even less successful twin-engined steam-powered aircraft before giving up his aircraft experiments. 29 April – Chuhachi Ninomiya flies the first model airplane in Japan, a rubber-band-powered monoplane with a four-bladed pusher propeller and three-wheeled landing gear. It makes flights of . The next day it flies . 1892 February – The first contract is awarded for the construction of a military airplane: Clément Ader is contracted by the French War Ministry to build a two-seater aircraft to be used as a bomber, capable of lifting a 75-kilogram (165-pound) bombload.

Lawrence Hargrave demonstrates a human-carrying glider in Australia at an aeronautical congress in Sydney. It is based on the box kite, an invention of Hargrave's.

Tethered to the centre of a circular track, its rear wheels rose while front wheels remained on ground. 1894 Czeslaw Tanski successfully flies powered models in Poland and begins work on full-size gliders. Railway engineer Octave Chanute publishes Progress in Flying Machines, describing the research completed so far into flight. Chanute's book, a summary of many articles published in the "American Engineer and Railroad Journal", is a comprehensive account on the stage of development worldwide on the way to the aeroplane. Otto Lilienthal's Normal soaring apparatus is the first serial production of a glider. Using different aircraft constructions he covers distances of up to .
