The Prince and Princess of Wales joked about the ‘wonderful British summer weather’ in an Instagram post
Kate Middleton and Prince William capped off their family fun on Friday with a group photo.
The Prince and Princess of Wales, both 41, took their three children for a fun-filled day at the Royal International Air Tattoo at Royal Air Force (RAF) Fairford in Gloucestershire, England. The Royal Family smiled in a group photo posted to Instagram, showing Prince George, 9, and Prince Louis, 5, protected in their raincoats – and they laughed at the wet conditions!
“A family day out at @airtattoo – in the wonderful UK Super summer weather to explore the C-17 and meet the crew of @usairforce,” the caption read.
Princess Charlotte, 8, went without a raincoat like her parents but pulled her hair back after wearing it earlier.

The family attended the largest military air show in the world, which attracts more than 200,000 visitors each July. The event is a benefit to the Royal Air Force Charitable Trust, which supports the Air Force and encourages young people to get involved in aviation.
The official caption of the Prince and Princess of Wales’ Instagram post continued, saying: “Congratulations to the brilliant winners of the Road to RIAT competition for designing a sustainable aircraft for the future of the RAF. ”
Another photo showed the children having fun at the scene, with Prince George touching some equipment as his father laughed behind him. The rest showed Kate meeting attendees at the event, shaking hands and sparking conversation.
The Princess of Wales met cadets and stopped by the Techno Zone during her visit. The Techno Zone aims to inspire young people to learn more about science, technology, engineering and math and to consider careers in engineering, aviation and aerospace.
She also met the winners of Road to RIAT, a year-long competition which challenged students from 300 schools across the UK to design a sustainable aircraft for the future of the RAF.
“The family were looking forward to the trip,” a royal source told PEOPLE of the unannounced outing, which was a school holiday treat for children in Wales. The trio recently finished school at Lambbrook School and are likely excited for summer vacation.
The family also has a special connection with the branch. Prince William flew for the RAF Search and Rescue Force based at RAF Valley in Anglesey, Wales from 2010 to 2013 and is Honorary Air Commander of RAF Coningsby and Princess Kate is the Honorary Air Cadet Air Commodore.
