(CBS) Prince William and Kate reunited on Thursday to attend the opening of a children's cancer ward.
The Duke and Duchess of Cambridge, both 29, were on hand at The Royal Marsden Hospital's Oak Centre for Children and Young People in Sutton, to tour the facility and meet medical staff, patients and their parents.
The event came after William pulled an all-nighter flying emergency helicopter rescue missions.
According to reports, the prince, a Royal Air Force search-and-rescue pilot, ferried a serviceman from a warship off the Isle of Mann to Sandhurst in Surrey to see a seriously ill relative. He also helped pick up a casualty with serious head injuries in Snowdonia during the 24-hour shift.
When his shift ended Thursday morning, William headed straight to the event. The Duchess of Cambridge had been staying in London (where she wason Monday) and reportedly arrived with palace staff.
Kate arrived in a cream Amanda Wakeley dress and her L.K. Bennett nude heels, according to the Daily Mail, while William sported a navy suit.
William was named president of The Royal Marsden Hospital in May 2007, a position previously held by his late mother, Diana, Princess of Wales.
