It was family day at the East Anglian Air Ambulance Base in Cambridge, England, on Wednesday, as Queen Elizabeth and Prince Philip visited Prince William on the job.
William -- who arrived at the base just 20 minutes before his grandparents after being called on a mission for a medical emergency that morning -- happily gave his grandparents a tour of the facility, where he's been working as a pilot for the last year.
But the Queen wasn't just there to check on William (or to show off her classy pink Karl Ludwig ensemble); she was on hand to officially open the East Anglian Air Ambulance's new base, the Egerton-Smith Centre.
After their tour, the Queen met some of the doctors and paramedics that work alongside Prince William.
Prince Phillip also got in on the action.
And they all enjoyed a good laugh before saying goodbye.
Last week, William and Kate Middleton took their 2-year-old son, Prince George, to the Royal International Air Tattoo at RAF Fairford, Gloucestershire, where the little one was thrilled to be checking out all the helicopters and aircrafts -- until he wasn't.
