Prince William and Princess Catherine of Wales made it a family day!

The Prince and Princess of Wales brought their three children – Princes George and Louis, and Princess Charlotte, on a visit to the Air Tattoo at RAF Fairford on Friday afternoon (July 14).

The young royals got a chance to check out a C17 plane and learned about the vehicles and aircrafts that the RAF has in its arsenal during the event, which is the largest miliary air show in the country.

During their private tour, George was seen pushing a button to help raise the ramp to the plane, while Louis was spotted hanging out on a small military vehicle.

William is Honorary Air Commodore of RAF Coningsby and Catherine is Honorary Air Commodore of the Air Cadets.
