Answer:
designing planes that could fly at more than five times the speed of sound.
Step-by-step explanation:
After two years of working on the West Area computer, Mary Jackson was invited to work with engineer Kazimierz Czarnecki, on the Supersonic Pressure Tunnel. This was a 60,000 horsepower wind tunnel that was capable of blasting models at over twice the speed of sound. So, designing planes that could fly at more than five times the speed of sound.
