An appeal has been launched to help buy an air ambulance to cover Bedfordshire.
The aircraft would serve Cambridgeshire and Bedfordshire
The East Anglian Air Ambulance already covers Cambridgeshire, Suffolk and Norfolk, but the charity wants to lease another BK117 helicopter.
By taking on a second helicopter, the operating costs will more than double to £250,000 per month.
An appeal was launched on Tuesday for the second aircraft to be based at RAF Wyton, near Huntingdon, and to cover Cambridgeshire and Bedfordshire.
The charity hopes to start operating the helicopter some time in late summer if funds permit.
