I am by no means a space history buff. That said, I believe I know some very basic stuff: Alan Shepard was the first American into space, John Glenn was the first American to orbit the earth, Neil Armstrong and Buzz Aldrin were the first men on the moon. Importantly, I know that none of those men died on their respective missions. Very basic stuff. So the fact that Hidden Figures had me on the edge of my seat wondering if John Glenn would survive re-entry into the atmosphere is a real testament to the film.
