American Airways  Stinson U   NC12121                  (c/n  9009)

                                       

                                           The Stinson U was a development of the earlier Stinson T (or Model SM-6000-B as it should
                                           more correctly be known).    This aircraft had a short plane between the outboard engines and
                                           the fuselage thus making it, more or less, a sesquiplane.    Introduced in 1932, the big Stinson
                                           was the ultimate in luxury air travel at the time.  American had a dozen or so of them and they
                                           were used mainly on the mid-western routes out of Chicago.
