About: T. J. O'Malley

Thomas Joseph O'Malley (October 15, 1915 – November 6, 2009) was an Irish-American aerospace engineer who, as chief test conductor for the Convair division of General Dynamics, was responsible for pushing the button on February 20, 1962, launching the Mercury-Atlas 6 space flight carrying astronaut John Glenn, the first American in orbit. Five years later, NASA asked North American Aviation to hire him as director of launch operations to help get the Apollo program back on track after the Apollo 1 command module fire on the launch pad killed three astronauts. O'Malley continued to play a leadership role in the United States' space program through the first Space Shuttle launch in 1981.
