The Devon Air Ambulance was launched in 1992, but the story started in 1986 when 18-year-old Ceri Thomas was knocked from his bicycle.

A road ambulance took him to hospital where, sadly, he later died of his injuries.
Ceri's mother, Ann, asked the doctors if anything could have been done to save her son.
She was told the quicker a patient receives treatment after an accident, the greater the chance of their survival.
Those few words planted the seed and the start of a mammoth fundraising project to launch Devon's first Air Ambulance in August 1992.
The trust now operates two helicopters, 10 hours a day, 365 days a year.
Between them they can reach 50% of Devon within five minutes, and the remainder within 20.
Devon's extensive road network, the remote countryside and rugged coastline mean precious minutes can be saved by the deployment of the air ambulance to the scene of an accident or medical emergency.

The BBC Radio Devon Air Ambulance Appeal hopes to raise the rest of the money needed for the charity to be able to place an order for a brand new purpose-built air ambulance in a year's time; some £600,000.
It will replace the current leased helicopter.
The charity decided buying - rather than leasing - a helicopter was a more efficient way of spending the hard-earned funds raised each year.
They bought a Eurocopter EC135 in 2008, replacing the then leased Exeter-based Air Ambulance.
Each year the trust must raise £4 million in order keep the two air ambulances airborne.
The helicopter will operate from the new airbase, just opened at Eaglescott Airfield near Umberleigh.
During the course of the appeal BBC Radio Devon will have unique access to the pilots and paramedics who make a difference to so many lives each week.
Reporters from radio, television and the BBC Devon website will take to the air with the crew on operations to give audiences an incredible insight into the work they do at incidents across the county.

Heléna Holt, chief executive of the Devon Air Ambulance Trust said: ''We are extremely excited to be working in partnership with BBC Radio Devon for the next 12 months.
"This campaign will give a unique insight into not only what the helicopter does, but how the money is raised to keep both helicopters airborne, as well as the people behind making it possible."
Mark Grinnell, BBC Radio Devon's managing editor added: "In 2004, BBC Radio Devon listeners helped the station raise more than £1m for the Chestnut Appeal for Prostate Cancer.
"If our experiences during the Chestnut Appeal are anything to go by, we will be overwhelmed by the generosity and willingness of people to get involved."
