Pardon me, TW and others, for veering into aviation once more. I know there are several here who share an interest in the history of aviation. In this case there is a very strong motor vehicle connection.
I have just stumbled on a quite amazing set of pictures of Willow Run, once the site of Henry Ford's farm and converted during the war into a massive airfield and factory making B-24 Liberators. There are no fewer than 291 slides, many of excellent quality. I hope you enjoy wasting as much time sifting through them as I have.
