Prince William and Kate Middleton are continuing to honor Prince Philip following his death at the age of 99. The Duke and Duchess of Cambridge attended the Duke of Edinburgh's intimate funeral service over the weekend and on Wednesday, the couple paid a special tribute to Philip during a visit to the Air Cadets 282 East Ham Squadron. Kate took over the royal patronage for the Air Cadets from Philip in 2015 before he retired from royal duties a few years later.
