Prince William and Kate Middleton's children have taken their summer break to new heights.

On July 14, the Prince and Princess of Wales brought Prince George, 9, Princess Charlotte, 8, and Prince Louis, 5, on a visit to Royal International Air Tattoo, the world's largest military air show, at the Royal Air Force Fairford in Gloucestershire, England. This marked the first public outing for the kids since King Charles III's Trooping the Colour birthday parade in June. 

The Wales children stole the show during the visit to the RAF base, where they were given a private tour of the facility's various aircraft.

According to HELLO! magazine, the group first went on board a C-17 transporter aircraft, which was used to carry the late Queen Elizabeth II's coffin in the days leading up to her funeral last September—and George, who turns 10 later this month, helped raise the ramp with the push of a button. Louis, meanwhile, adorably chilled out in a small military vehicle. 

George, now the second-in-line to the throne, wore a blue polo shirt and blue pants, paired with brown suede boots that matched his dad. Charlotte sported a navy and white striped, sleeveless dress with a Peter Pan collar, paired with a white cardigan, while Louis arrived in a blue polo top with khaki shorts. The two youngest kids also wore matching navy and white slip-on sneakers.

Kate wore a beige pinstripe Blazé Milano blazer over a white top and navy pants, while William opted for a navy suit with no tie.

The event and venue holds a special place in William's heart, as he used to work as an air ambulance pilot for the East Anglian Air Ambulance in England and a helicopter pilot for the RAF Search and Rescue Force before announcing plans to concentrate on his royal duties in 2017. He is currently an Honorary Air Commodore of RAF Coningsby, while Kate bear the title of Honorary Air Commodore of the Air Cadets.
