Want to learn to fly a helicopter? In this album Royal Berkshire Ambulance pilots show two complete beginners the ropes. Normally, Marie and Tracey dispatch air ambulances, now they find out how to fly one. The five video tracks offer a hands-on explanation of the science and engineering behind helicopter flight. They show how rotors help this tonne of metal take off, change direction and gain speed. They explain the difference between traditional and cutting edge military technology, and demonstrate what happens in an emergency landing. This material forms part of the course S207 The physical world.
