In "Surly you're joking my Feynman" there is the story of RF talking to the painter who teaches him to mix paints, and the colours you need to get make yellow. Turns out you should talk to the person who's been mixing paints all their working life. Isn't there a similar story after the challenger accident where he talks to the maintenance people on the ground?
