Part 40 of Wonders of World Aviation was published on Tuesday 6th December 1938, price 7d.
This part concluded the series.
The cover on this week’s Part shows a K.L.M.Douglas DC-3 taking off. Douglas DC-3 air liners made under licence in Holland for K.L.M. have a cruising speed of over 170 miles an hour and a maximum speed of 212 miles an hour. The maximum rate of climb is 700 feet a minute. Each machine has two Wright Cyclone nine-cylinder radial air-cooled supercharged engines, rated at 850 horse-power at 2,400 revolutions a minute at 5,800 feet. The aircraft are intended mainly for day flying, normally seat twenty-one passengers and have a steam-heating system for the cabin.
The Glossary of Aeronautical Terms included in this Part was due to the many requests received by the Editor for the inclusion of an explanation of some of the terms more frequently used in connexion with aviation. Advanced technical descriptions have been avoided and the explanations given in a manner that all will be able to follow.
The pages of this Part are largely taken up by an index for the two volumes. The value of this index to WONDERS OF WORLD AVIATION cannot be overrated. The index turns the weekly parts into a complete reference work in which readers may quickly turn to authentic information on almost every aspect of aeronautics. The index has been prepared by members of my staff who are familiar with all the chapters. Thus it has been possible to ensure that the entries are not only complete but are also classified in a manner best calculated to enable the reader to find any desired entry in the minimum of time. The index has been prepared week by week as each new Part was printed. Tests of the value of the entries have therefore been possible over a long period. This has ensured that no valuable item of information has been omitted from the index pages.
