Working in partnership with the Scottish Ambulance Service (SAS), Scotland's Charity Air Ambulance (SCAA) is an integral part of Scotland’s frontline emergency response network, responding to trauma incidents and medical emergencies across the country, covering an area of more than 30,000 square miles.
The SCAA responds, on average, to one time-critical emergency call out every single day.
