This paper reviews the benefits to be derived from the implementation of a successful large scale VTOL passenger service and examines various studies, including the Northeast Corridor VTOL Investigation, which show that suitable aircraft will be available starting in the middle 70's, and that VTOL service can be economically attractive if an operating environment is created that is optimized for VTOL aircraft. If an optimized environment is not created, the implementation of successful VTOL service is very doubtful. Particularly important aspects of the operating environment, such as an air traffic control system; landing and navigation systems, vertiport location and operating regulations, are discussed.
