17269 Dicksmith           Discovered 2000 June 3 by J. Broughton at Reedy Creek Observatory.
A big-hearted Australian and avid adventurer, Dick Smith (b. 1944) made the first helicopter flight around the world in 1983 and to the north pole in 1987. On a bet last year he accomplished a balloon flight from New Zealand to Australia against the prevailing wind.
