The Prince of Wales provided a foreward for the programme where he reflected on his days as an airline pilot.
"During my time as an air ambulance pilot, I took great pride in being part of a team that delivered such vital work, knowing that in a small way I could play a role in giving someone a chance of survival," he said.
"Now, as Patron of London's Air Ambulance Charity, I am honoured to represent the service and help raise awareness of its life saving work.
"Whatever you do for the charity whether on the frontline, a charity employee, a volunteer or a supporter you are part of the team that makes sure when someone is critically injured, expert medical care can arrive within minutes."
