Golden West Airlines  Beech 99   N954SM            (c/n  U67)

                                    

                                        This Beech 99 came from Skymark Airlines, a Sacramento-based commuter carrier of the late
                                        1960s.  I am not sure if it was the intent of Golden West at one time to introduce this type as a
                                        Twin Otter alternative or not.  In the event it was sold off to Air Wisconsin after very little use.
                                        I found it lurking among the Twin Otters one day at Long Beach in 1969.
