Generally known as the "jump jet", the Harrier uses the unique properties of 'four-poster' vectoring-thrust technology for short or vertical take-offs and landings. Thus it is not dependent on the runways that would be among the first casualties of a major war. Yet this British invention, developed from a French idea with American money, long remained little more than a toy. The Harrier was slowly proved in British and American service, and the Falklands campaign of 1982 showed how capable and essential this type really is. This is a superbly illustrated account of the Harrier.
