Continuity mistake: When Katherine realises she can use Euler's Method to calculate how to bring John Glenn safely back to earth, she is seen wearing a wristwatch when she's at the chalkboard. The watch is not on her when she leaves to get a book about Euler's Method. It reappears when she's back at the chalkboard.

Continuity mistake: In the last scene in which Vivian gives Dorothy an assignment, her lanyard is at first hanging neatly from her neck. The camera goes back and forth between her and Dorothy, and when you last see Vivian, the ball chain for the lanyard is no longer hanging neatly; it is pulled to the side because it's caught on her jacket lapel.
