granfer, just for info the Devon Air Ambulance trust currently runs two EC135s, the original machine was retired some years ago after sterling service. One of them is leased however so the Radio Devon appeal is to purchase a second helicopter to replace the leased one.
As a Devonian living near Chivenor the 'yellow helicopters' will be sorely missed. They are part of North Devon and it won't be the same not seeing them overhead.
