This little snapshot of history gives us an example of how our industrial might helped win WWII. The plant is Willow Run, a Ford designed facility strictly for production of B-24 Liberator bombers. At it's peak in 1944, six hundred fifty bombers were built every month.
But, that was during the heady days of Smokestack America. We've got a service industry now.
