14 July – Orville Wright has a serious crash with Wright Flyer III, upon which the Wright Brothers radically alter the aircraft. The front rudder is mainly the culprit for the Flyer's insistent pitching.
18 July – Daniel Maloney launches a tandem-wing glider designed by John Montgomery at Santa Clara, California. A balloon cable damages the glider and upon release Maloney and the aircraft fall uncontrolled to the ground, killing Maloney.

7 September – Flying circles over a cornfield near Dayton, Ohio, and chasing flocks of birds, Orville Wright records history's first bird strike. The dead bird lays on the airplane's wing before Wright makes a sharp turn and dumps it off.
4 October – Piloting the Flyer III over Huffman Prairie outside Dayton, Ohio, Orville Wright makes the first airplane flight in history of over 30 minutes in length.
