The Ford V8 Times had an article (across several issues) that told about the Ford plant and building the bombers. Ford built a plane in something like 10% of the man-hours that the airplane folks did.....they also invented tooling that, for instance, did the drilling of the wing attachment locations so all planes could accept any wing....a unique idea at the time. Ford built airplane "kits" that were essentially a crate airplane that could be assembled overseas....another novel idea. The Ford bomber plant was a huge scheduling task....even getting people to and from their work stations was a task. I read that street cars would arrive bringing people for a shift and would empty to be filled by the previous shift going home. This airplane was all done on paper....zero computers but probably lots of carbon paper.....no Xerox machines either. Ford embarrassed the airplane folks, they had poo'd the idea of Ford even being able to build an airplane.
