On 13 July 2016 HM the Queen opened the new base of the East Anglian Air Ambulance (EAAA), where her grandson works as a helicopter pilot. Joined by the Duke of Edinburgh, she visited the charity's new operating base at the Egerton-Smith Centre at Cambridge Airport. The royal couple were given a tour by the Duke of Cambridge, who has been based in the city for more than a year. As part of the tour they viewed one of two operational H145 helicopters before unveiling a plaque. The Queen and the Duke of Edinburgh also met some of the charity's medics, support staff and pilots. The East Anglian Air Ambulance Service was launched as a charity in 2000. The organisation's pilots fly an average of five missions per day from bases in Cambridge and Norwich and cover a wider geographical area spanning Norfolk, Suffolk, Cambridgeshire, Essex, Bedfordshire and Hertfordshire.
