Air travel at 600 m.p.h. to 650 m.p.h. in the next decade and the use of multi-seat twin rotor helicopters on internal air routes to help to solve terminal delay problems, bring in their train growing problems of Air Traffic Control. Full use of high speed civil transports and helicopters does not seem practicable within the British Isles unless the problem of the siting of landing strips is reviewed and unless ideas on this subject are recast in the light of growing experience.

To the commercial airline pilot Great Britain is indeed a “tight little island.” It will appear smaller yet when the de Havilland Comet jet air liner operates to time-tables of approximately double the speed of most of the existing schedules of today.
