From the exploits of pioneers to the rapidly expanding services of today. The air routes of South Africa, dealt with this week by Sidney Howard, are fitting reminders of Africa’s debt to aeronautics. Sir Alan Cobham’s pioneer Empire flights, the story of which was begun in Part 10, 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.
Recent events in Europe have brought me a number of inquiries about the air fleets of foreign countries. It is well known that for various reasons the exact state of aviation abroad is not readily ascertainable. Some of my readers have wondered if, because of this, it will be impossible to make our survey of the air a world-
An Airspeed Envoy Passenger Aeroplane
AN AIRSPEED ENVOY PASSENGER AEROPLANE used by South African Airways. Four of these aircraft are in use on services in the Union of South Africa. They an be converted for military purposes, and three similar machines have been acquired by the South African Air Force as fast medium bombers. When used for commercial purposes the machines accommodate six passengers. They have two Armstrong Sidddeley Cheetah IX engines.
Converting air photographs into conventional maps. This is another fascinating chapter in the series on Air Photography, by Squadron Leader P. R. Burchall. This subject has so many facets of interest that only the recognized expert can deal faithfully with it. Many readers who have not appreciated the significance of air photography will be interested to know of
its amazing applications. In one air photograph, taken in America, a range of mountains that was 600 miles away from the camera was clearly visible. Our contributor tells in this chapter of the methods by which flying maps are made.
