Prince William, Kate Middleton's kids steal the spotlight during royal outing

Prince George, 9; Princess Charlotte, 8; and Prince Louis, 5, accompanied their parents to a Royal Air Force station

Being a royal family member certainly has its perks.

Prince William and Kate Middleton on Friday took all three of their children — Prince George, 9; Princess Charlotte, 8; and Prince Louis, 5 — on a royal outing to a Royal Air Force station. The royals got the chance to look at the insides and outsides of a variety of planes as preparations are being made for this weekend's Royal International Air Tattoo show, the world's largest military air show.

The mood seemed to be a mix of excitement and deference as the family also explored the exact C-17 transporter aircraft that flew the body of Queen Elizabeth from Edinburgh — which is near Balmoral Castle, where she passed away last year — back to London.

It wasn't solely a trip to pay tribute to the late Queen, however — they also saw various jets, helicopters and more.

While they were there, they also saw a bit of a preview of the upcoming air show.

Upon their arrival, a few aircraft were in the sky, but as the rain began pouring down, that part of the family outing ended.

The Prince and Princess of Wales also took their young princes and princess to Techno Zone, an area on the airfield that offers hands-on learning experiences for children, namely in flying an aircraft but also in other areas of the STEM field.

True to form, the family was impeccably dressed as they explored the airfield. Middleton, known for her keen fashion sense, appeared in a pair of ankle-length navy pants with a cream-colored top tucked in and a beige and white pinstriped double-breasted blazer on top.

Charlotte wore a white and navy-striped dress with a white cardigan with navy slip-on sneakers with her hair tied back in braids.

Blue seemed to be the color of the day, as William chose navy pants and a blue patterned blazer over a light blue shirt and George had on a blue polo with green chinos.

Little Louis stole the show as always in navy shorts, a navy sweater with a white collar peaking out and a pair of shoes that matched his big sister's.

The Prince and Princess of Wales clearly had a good time, even with the rain, tweeting, "A family day out at the @airtattoo - in the wonderful British summer weather," adding an umbrella emoji. "Great exploring the C-17 and meeting @usairforce crew." 

Besides the family fun and the small tribute to Queen Elizabeth, William and Middleton have additional ties to the Royal Air Force.
