BBC Leicester's Jules Benham took to the skies with Derbyshire, Leicestershire & Rutland Air Ambulance (DLRAA), to find out what goes on behind the scenes of the emergency teams. The days starts at first light, around 7:00 in winter.
The air ambulance aim to get senior doctors to the scenes of incidents as quickly as possible, and to swiftly transport casualties to nearby hospitals for specialist treatment. Here Captain Pete Barnes grabs some breakfast before their first call.
The air ambulance team is based at East Midlands Airport. Each team includes a pilot, paramedic and doctor to provide life-saving treatment to around 2,100 square miles of the region, covering in excess of 1.4 million people.
The DLRAA is a registered charity and relies on public donations, fundraising activities and sponsorship to keep running. Here Dr Pam Hardy checks the map on route to the first call of the day.
The average cost per call-out is around £1000, with the annual basic running cost of the service working out at over £1.5 million. The crew grab spectacular views of the Leicestershire countryside on their missions.
Dr Pam Hardy takes a look at the stunning scenery in the clear sky. She also keeps an eye out for other nearby aircraft.
It is essential that the team get to casualties as quickly as possible. Helimed 5-4 can be airborne in just 45 seconds and can reach a top speed of 200mph.
As well as a speedy response, another benefit of the air ambulances is their ability to land in places emergency land vehicles cannot reach without difficulty. For this call-out the helicopter was able to land in a nearby field.
This vehicle had skidded on icy roads in the East Leake area and lost control of the car. The air ambulance team were able to reach the casualties in minutes, before other emergency services vehicles.
The rapid medical attention can make a life or death difference to a patient. Here the crew fly over Ratcliffe-on-Soar Power Station.
Pilot Captain Pete Barnes is accompanied at the cockpit by paramedic Dave Roberts. Pete is very used to controlling helicopters, having done stunt flying for James Bond films. Dave has worked in the Ambulance Service for over 10 years.
The high-tech helicopter must be refuelled after every mission as they crew never know where they will be called out to next.
The air ambulance crew will not necessarily transport patients to the nearest hospital, but the one that will offer the best specialist care for a specific person's needs.
From the base at East Midlands Airport, at top speeds it can take less than six minutes to reach the Leicester Royal Infirmary, five to reach hospitals in Derby and just three to reach the Queen's Medical Centre. Here the helicopter flies over Nottingham.
Being part of the air ambulance team can involved a lot of multi-tasking. Here Dr Pam Hardy uses bolt cutters to clear the way through barbed wire to an injured woman.
During the day Jules spent with the team she saw first hand how swiftly the helicopter could reach difficult places, like the Derbyshire Peak District.
Here the air ambulance crew join Mountain Rescue to treat and transport a man who has fallen whilst climbing.
The helicopter has low vibration, to keep patients stable, and enough cabin space for two stretcher patients to be treated on route to the hospital. Here the injured climber is transported for specialist treatment on the ground.
