Agreed, I delivered to the Chrysler assembly plant in Newark De, for almost a year. I got to see most of the operations, from many angles. Watched many times when the line hiccuped, and the technicans came and had to assess, and repair the issue, with all the top management watching. I have no doubt they knew more about the workings of the line, then the engineers that designed it. Would be A great job, but I do not know how one would start out. You cannot see how many sections work, unless the section is locked out, which means at least that portion of the line is shut down. I do not know how many times they were called upon for the average shift, but I bet most times were under pressure to get things fixed fast.
