Pacific Southwest Airlines  Douglas DC-3  N95487             (c/n  4225)

                                    

                                           By the early 1950s Pacific Southwest Airlines was known universally as PSA.  Many passengers
                                           did not even know (or probably care) what the initals stood for.     This also was the era of the
                                           impossibly tiny registrations painted on the fin.   This DC-3 was built as a US Navy R4D-1 (BuAer
                                           3134) and civilianized in 1948.  PSA sold it off to Piedmont Airlines as N57V.  This shot was taken
                                           at San Francisco, circa 1952.
