A Royal Air Force Sea King Search and Rescue helicopter from 203 Squadron RAF is pictured during Exercise Yellow Scorpion with the RNLI (Royal National Lifeboat Institute). The helicopter was piloted by newly qualified SAR pilot HRH Prince William.

William's first rescue mission as co-pilot of an RAF Sea King was a response to an emergency call from Liverpool Coastguard on 2 October 2010. In November 2011, he participated in a search-and-rescue mission involving a cargo ship that was sinking in the Irish Sea; William, as a co-pilot, helped rescue two sailors.
