Worth and at General Electric where he was responsible for re-entry systems, he became Deputy Associate Administrator for the Space Shuttle Program prior to the first launch of Columbia in 1981. After the trauma of Challenger, he continued to contribute in key positions in the National Aerospace Plane (X-30) and Orbital Sciences X-34 programs in a career that spanned 56 years.

Thornton “T” A. Wilson

BS, Aeronautical Engineering, 1943
Chairman of the Board of Directors, The Boeing Company
Inducted 2004

From Sikeston, Missouri, “T” Wilson graduated from Iowa State in aeronautical engineering in the class of 1943 and joined The Boeing Company. The first airplane to bear the Wilson imprint was the dramatically new B-47 swept-wing bomber. Wilson was the overall project engineer of the B-52 program during the latter stages of its design, and he led the proposal team for Boeing that won the Minuteman ICBM program. Wilson was elected vice president of Boeing in 1963 and was named company president in 1968 and chief executive officer in 1969, a position he held until 1986. Awards received include the James Forrestal Award in 1975, the Wright Brothers Trophy in 1979, and the 1982 Collier Trophy. Wilson also received the National Academy of Science Award for Aeronautical Engineering and the Daniel Guggenheim Medal. In 1983, he was inducted into the National Aviation Hall of Fame for his achievements during his Boeing career. In 1989, he was inducted into the National Business Hall of Fame. Wilson is also a member of the National Academy of Engineering.
