17 January – Gustave Whitehead claims a circling 11 km (7 mi) flight over water in a 40 hp- 29.9-kW- engine-powered flying machine with wheels and an amphibious boat-shaped hull. He supposedly makes a water landing near his starting point, and helpers pull him from the water.
October 1902. – The Wright brothers complete development of the three-axis control system with the incorporation of a movable rudder connected to the wing warping control on their 1902 Glider. They subsequently make several fully controlled heavier than air gliding flights, including one of 622.5 ft (189.7 m) in 26 seconds. The 1902 glider is the basis for their patented control system, still used on modern fixed-wing aircraft.
