[[table]]

1 1968 estimate derived from Table No. 24.  Indicated diversion percentage believed attainable two to five years after suburban helicopter service is inaugurated.  Suburban services probably will not operate prior to 1965.  Since the volume of railroad commutation passengers has been gradually declining for many years, it is not reasonable to hold the 1954 estimate (Table 24) at a constant until 1968.  The rate of expected helicopter growth increases at a decreasing rate as shown above.
