Mac McCool

Alexander “Mac” A. McCool Jr.
“He was heavily involved in the design of the propulsion systems for the SATURN launch vehicles. In 1969, as Chief of the Systems Project in the Office in the Marshall Space Flight Center’s Astronautics Laboratory, he directed project engineering for the SATURN/APOLLO and SKYLAB programs. In the 1970s, as the Director of Structures and Propulsion Laboratory, McCool assumed the leadership role in the early Development of the Space Shuttle’s Main Engine and in the early ’80s, managed the in-house development, test and flight phases of the Space Shuttle Solid Rocket Boosters. After the Challenger accident in January 1986 Mr. McCool was selected to lead the Solid Rocket Boosters recovery activity at the Kennedy Space Center. His expertise made him a valuable commodity at NASA, being named Director of the Safety, Reliability, Maintainability, and Quality Assurance Office at the George C. Marshall Space Flight Center.”
