The Duke of Cambridge showed his son the inner workings of a helicopter and the cockpit of a Red Arrow Hawk as the family enjoyed a trip to the Royal International Air Tattoo at RAF Fairford.
Prince George wore blue ear defenders as William and the Duchess of Cambridge toured the world's largest military air show.
The two-year-old, wearing a white T-shirt and dark shorts, was pictured being led by the hand across the airfield after the family were greeted by Air Marshal Sir Kevin Leeson, chairman of the RAF Charitable Trust, and Air Chief Marshal Andrew Pulford, Chief of the Air Staff, RAF.
They met members of the Red Arrows display team in front of a Red Arrow Hawk, shortly before they took part in the show.
And George got a closer look at a Squirrel helicopter - the same aircraft William trained in while he was based at RAF Shawbury in 2009.
