This is the story of an aircraft, indeed a whole family of aircraft, each in its day revolutionary. This programme charts the remarkable success and progress of the world's first turbojet-powered airliner and its evolution into a front-line aircraft of the Royal Air Force. The Nimrod was the world's first land-based pure jet aircraft built for anti-submarine duties and long-range maritime patrol. The Nimrod's ability to detect surface and subsurface movements was outstanding and ensured that even under the waves the enemy had no place to hide.
