I just did a quick Indeed check on the Textron plant in Wichita. Average salary at the non-executive/non-senior management level averages around $75K. That’s a combination of everything from janitor to customer service/HR to engineering/manufacturing to logistics, sales, and marketing jobs. I’m not sure what your idea of a salary range average should be for a team putting together and supporting a jet you’d fly your family in. But I know it would not be neither my position nor my place to question the money the machinist tech is making assembling the wings.
