A solid manual that starts with a history of rockets and jets from the early Chinese and works its way through natural law explanations of jet principles, to the making of simple jet and rocket models, a high speeding flying wing and the installation and operation of jet engines. From the use of simple devices such as canned heat and a small boiler or a carbon dioxide cartridge and the light boats and cars that can be propelled by them, the author launches into a more detailed description of a small commercial dyna-jet engine, running it and installing it on a model plane. There is a fairly wide range of presentation from the simple to the complex -- the boilers and cartridges would be easy enough for a nine year old but the engines need some help. All told, a fair handbook with an adequate supply of photographs and drawings. Two observations more: it is not a book for makers of model planes; mention is always made of specific places to get materials.
