The air routes of South Africa are fitting reminders of Africa’s debt to aeronautics. Sir Alan Cobham’s pioneer Empire flights showed what great possibilities for improved transport were latent in Africa. These latent possibilities are now being further explored and developed, and it seems probable that aviation will play a more important part in the progress of Africa than in that of any other continent. The great distances to be covered, the large number of suitable alighting places, and the vastness of Africa’s resources render that continent exceptionally suitable for development.
This is the fourth article in the series Air Routes of the World.
