Pan American-Grace Airways   Sikorsky S-38B  N945M                     (c/n  314-3)

                                          

                                              In 1929 Pan American-Grace acquired a fleet of six of the ungainly looking Sikorsky S-38 twin
                                              engined twin boom amphibians.  The above shot (courtesy of Panagra) was taken at Cristobal in
                                              the Panama Canal Zone, the northern terminus of their routes to South America.   Incredibly, these
                                              ancient machines were flown on passenger and air mail schedules all the way to Lima, Peru.   The
                                              shot below of crew loading mail, although not identifying the individual aircraft (in all probability also
                                              NC945M), is interesting in that it gives a close up view of the passenger cabin.
