fly blind
Feel one's way, proceed by guesswork, as in There are no directions for assembling this furniture, so I'm flying blind. This hyperbolic expression dates from World War II, when it was used by pilots who could not see the horizon and therefore had to rely on instruments. It was transferred to broader use soon afterward.
