Never one to miss an opportunity to continue her education, Mary took FORTRAN classes, teaching herself to program. The computers that had made long-distance spaceflight possible were also revolutionizing aeronautical research, a specialty known as computational fluid dynamics. The engineers now conducted experiments in their beloved wind tunnels and then compared the results with simulations on their computers. Just as the electronic machines had taken the place of human computers in aeronautical research, the day would eventually come when the computer would displace the wind tunnel itself.
