The team covers 5,000 square miles and a population of 2.5 million with two helicopters.

The helicopters, which fly an average four missions a day, are kept in the air mostly by charitable donations - no mean feat considering they cost £250,000 a month.

Lynn News photographer Paul Tibbs spent a day flying with the hard-working crews, as the attached video shows, as part of a series of films about the work of the emergency services locally.

Lynn News readers have done their bit for the service, raising £66,000 for an illuminated, all-weather helipad at the town's Queen Elizabeth Hospital to allow the helicopters to land there 24 hours a day, work on the helipad now taking place.

"Chances of survival of greater if you reach hospital within one hour - the 'Golden Hour'," said an East Anglian Air Ambulance spokesman.
