Explanation:

Mary Jackson began her engineering career in an era in which female engineers of any background were a rarity; in the 1950s, she very well may have been the only black female aeronautical engineer in the field. For nearly two decades she enjoyed a productive engineering career, authoring or co-authoring a dozen or so research reports, most focused on the behavior of the boundary layer of air around airplanes. As the years progressed, the promotions slowed, and she became frustrated at her inability to break into management-level grades. In 1979, seeing that the glass ceiling was the rule rather than the exception for the center’s female professionals, she made a final, dramatic career change, leaving engineering and taking a demotion to fill the open position of Langley’s Federal Women’s Program Manager. There, she worked hard to impact the hiring and promotion of the next generation of all of NASA’s female mathematicians, engineers and scientists.
