I found this video in our archives at HistoricAviation.com. It shows the construction of the Ford Tri-motor. 199 were built from 1926 through 1933. These ships were the first all-metal airliners and were instrumental in introducing America to commercial air travel. The oldest surviving of these ships in NC-1077, Serial No. 10 built in 1927.
There are, in large chunks up to flying, perhaps 18 world wide. Of those 18 there are 5 capable of flying at more or less a moments notice. The ones which have flown in the last year include the EAA's, Grand Canyon's, Dolf Overton's (now for sale), and mine.
