East Anglian Air Ambulance (EAAA) is a 365-day-a-year helicopter emergency medical service (HEMS) covering Bedfordshire, Cambridgeshire, Norfolk & Suffolk. They exist to save lives by delivering highly skilled doctors and critical care paramedics by air to seriously ill or injured people in the region. They do not receive regular direct government funding and the £17 million they need to raise this year comes directly from charitable donations.
