Chicago Helicopter Aiorlines  Sikorsky S-61L  N301Y    (C/n  61-032)

                                      

                                              Flushed with the success of its Midway to O'Hare business, CHA order three Sikorsky S-61Ls in
                                              1959.  Unfortunately once most of the airlines had accomplished their moves from Midway to the
                                              new Chicago Airport,  traffic declined considerably and the company  postponed delivery of these
                                              large helicopters until 1962.    The development of high speed freeways in and around the Chicago
                                              area, plus the loss of air mail subsidies spelled the doom of not only CHA, but all the helicopter
                                              airlines.  CHA wentout of business sometime in the 1970s.
