As Bill Gunston says in his introduction: 'The aircraft described In this book is unique. By the seemingly simple process of vectored thrust it can take-off vertically, hover in the air, fly backwards or sideways, and land vertically. So can helicopters; but the Harrier can also make a running take-off burdened with a much heavier useful load, accelerate forwards over a sloping ramp that catapults it high into the air, fly at supersonic speed, and make "unbelievable' flight manoeuvres using viffing (vectoring in forward flight) so that the engine thrust pushes it round sharp corners. No helicopter can do this and. so far as we know in the West, neither can any other of man s flying machines.
I doubi if there is anyone remotely interested in aviation who is not broadly familiar with what a Harrier can do. Millions have watched the strange birds perform at air shows. But in 20 years the number sold has been trivial: for example, about 100 for the RAF and about 100 for the US Marines. One is left with two conclusions; either jet V/STOL ^vertical or short take-off and landing) is not worth having, or the world's air forces have got it wrong. And there is not the slightest doubt it is the second conclusion that is correct.'
This book by one of The world's outstanding aviation writers is thus more than just a technical description of a remarkable aeroplane. It examines the role of the Harrier in the defence of the West and it pulls no punches in its criticism of those in authority who throughout the Harrier's development have failed to grasp its significance and potential. Fully illustrated both with photographs and line drawings it makes an important and controversial addition to Ian Allans highly successful series.
