Prince William is to feature in part of a new BBC documentary through his work as an RAF search and rescue pillot. William, 30, can be seen talking openly about his job, saying he feels there is "no greater calling" in life than to try and save lives.
"There's no greater feeling than when you've actually done some good and saved someone's life" the royal explains during the programme, adding, "I don't think there's any greater calling in life … to be able to see a son or daughter's face when you bring their mother or father back from the edge of death – it's quite powerful."
The documentary, Helicopter Rescue, follows events at RMB Chivenor in Devon and RAF Valley in Anglesey, where the Duke of Cambridge is based.
This is not the first time Prince William, who is known at Lieutenant Wales when he's at work, has given an insight into his RAF life. In November 2012, new behind-the-scenes pictures were released showing a typical 24 hour shift for Kate Middleton's husband in his official capacity as a Search and Rescue (SAR) pilot flying Royal Air Force Sea King helicopters.
As well as explaining how each morning begins with a briefing from the previous shift's SAR crew, the photos also showed William as very much part of the team, being on-call for any emergency and making tea during the crew's down time.
William's appearance in Helicopter Rescue will air on BBC One Wales on 8 April.
