MR HAMMARSKJOLD In 1950 there were 31 million passengers on world scheduled air services. The estimate for the early 80s is 1000 million.

This explosive growth will present the civil aviation industry with some of its toughest and most crucial problems. Most will revolve around airport facilities.

The key to the proper planning of airports is adequate forecasting of future demands. This calls for the closest co-operation between what has been called the 'three solitudes' of the airport planning equation: the airport authorities, the airlines and the manufacturers.

Economic growth will largely determine future air travel demand. The OECD recently projected gross national product expansion in major world traffic generating areas to the end of the 70s at about the same level as that for the 60s.
