In Hidden Figures when John Glenn's rocket was about to be launched into space there was some uncertainty regarding the calculation results provided by IBM 7090. Al Harrison was discussing this with the astronaut:
AL HARRISON (ON PHONE)
The IBM has been spot on up to this point, John, but we’ll run it again, see what it comes up with.

To be honest with you, Al...when I fly, I fly the machine and now I feel like the machines are flying me.
We’re on the same page. We’re staying on the ground until this works out our way. Stay tuned.
Let’s get the girl to check the numbers.
Yes, sir. The smart one. If she says they’re good, I’m ready to go.
I'm curious if Glenn asking specifically for Katherine G. Johnson is a historical fact. The movie is based on a non-fiction book of the same name, I'm wondering if this event is described there or in any other source.
