                                            In the mid 1950s CHA expanded its service from Midway to include not only the new Airport at
                                            O'Hare, but also to Meigs Field on Chicago's waterfront and to Gary, Indiana in the south and
                                            Winnetka in the north.  To accomodate these new routes a fleet of S-58s was acquired. The above

                                            a little less noise for passengers.
