Following the initial appeal to the public for funds in 1986, the service commenced on 27 Aug 1992. In UK terms, Devon is a big county to cover. To reduce cost and establish a close liaison, the south Devon service is co-located with the Devon and Cornwall Police helicopter. After the success of this Exeter based service, a second helicopter was introduced in Apr 2005, based in north Devon to reduce flight times. It moved to its present purpose-built building on the south side of Eaglescott in early 2007. 
The Devon Air Ambulance Trust (DAAT) owns its two helicopters
