11246 Orvillewright           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
As the pilot of the Wright Flyer 1 in a 12-second flight on 1903 Dec. 17, Orville Wright (1871-1948) is generally credited, with the assistance of his brother, as being the first pilot of a heavier-than-air flying machine.
