8029 Miltthompson           Discovered 1991 Sept. 15 by H. E. Holt at Palomar.
NASA research pilot Milt Thompson (1926-1993) was the ninth pilot to fly the X-15 and made a total of 14 flights. He subsequently made the first flights of the M2-F1 and M2-F2 lifting bodies, which were the forerunners of the Space Shuttle.
