Many years later, Katherine Johnson would say it was just luck that of all the computers being sent to engineering groups, she was the one sent to the Flight Research Division to work with the core of the team staffed on an adventure that hadn’t yet been conceived. But simple luck is the random birthright of the hapless. When seasoned by the subtleties of accident, harmony, favor, wisdom, and inevitability, luck takes on the cast of serendipity.

Many years later, Katherine Johnson would say it was just luck that of all the computers being sent to engineering groups, she was the one sent to the Flight Research Division to work with the core of the team staffed on an adventure that hadn’t yet been conceived. But simple luck is the random birthright of the hapless. When seasoned by the subtleties of accident, harmony, favor, wisdom, and inevitability, luck takes on the cast of serendipity. Serendipity happens when a well-trained mind looking for one thing encounters something else: the unexpected. It comes from being in a position to seize opportunity from the happy marriage of time, place, and chance. It was serendipity that called her in the countdown to John Glenn’s flight.

The first courses imparted the basics of aerodynamics. For a wing moving through the air, the slower-moving air on the bottom of the wing exerts a greater force than the faster-moving air on the top. This difference in pressure creates lift, the almost magical force that causes the wing, and the plane (or animal) attached to it, to ascend into the sky. Smooth air flowing around the wing means the plane can slip through the sky with minimum friction, the way the most efficient swimmers cut through the water. Turbulent flows, like the swirl and churn of rapids in the water, resist the plane, slowing it down and making it harder to maneuver. One of the NACA’s great contributions to aerodynamics was a series of laminar flow airfoils, wing shapes designed to maximize the flow of smooth air around the wing. Aircraft manufacturers could outfit planes with wings based on a variety of NACA specifications, like choosing kitchen appliances from a catalog for a new house. The P-51 Mustang was the first production plane to use one of the NACA’s laminar airfoils, a factor that contributed to its superior performance.

But by leapfrogging the United States into space, the Russians had turned even local racial policy into fodder for the international conflict. In forcing the United States to compete for the allegiance of yellow and brown and black countries throwing off the shackles of colonialism, the Soviets influenced something much closer to Earth, and ultimately more difficult than putting a satellite, or even a human, into space: weakening Jim Crow’s grip on America.

“Eighty percent of the world’s population is colored,” the NACA’s chief legal counsel Paul Dembling had written in a 1956 file memo. “In trying to provide leadership in world events, it is necessary for this country to indicate to the world that we practice equality for all within this country. Those countries where colored persons constitute a majority should not be able to point to a double standard existing within the United States.”

Dorothy’s insistence also had a collateral effect: one of the white computers in the branch, in the same limbo position as Katherine, had herself gone to Pearson to petition for a raise.
