11778 Kingsford Smith           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Charles E. Kingsford Smith (1897-1935) was an Australian pilot who flew from America to Australia across the Pacific (1928) and from Europe to America from east to west (1930). Both flights were done with the Fokker F VII "Southern Cross". He died when his plane went down over the Indian Ocean near Burma.
