We go behind the scenes of the Dorset and Somerset Air Ambulance to see how it operates and the challenges it faces as an emergency service run by a charity.

We revisit some of our previous World War Two era restoration features to see how they have progressed and where they are on the journey to completion.

We are joined by pilot and TV presenter Arthur Williams to talk about his new Channel 4 television programme ‘Flying Across Britain’, a journey he carries out in a wonderful Piper Cub.

We are joined by Rainer Groh, PhD MEng, Royal Academy of Engineering Research Fellow from the Department of Aerospace Engineering at the University of Bristol.
