The Welsh family of three, Prince George, Princess Charlotte, and Prince Louis, have begun their summer vacation. The family of five attended the Royal International Air Tattoo yesterday, touring the C-17 Globemaster III that transported the body of Queen Elizabeth, who died last September, to London; according to People, when the sound of the large plane was heard in the video of their tour, Louis looked startled and shouted in his ears He yelled in surprise, covering his ears. (Remember, the first iconic gesture was made as planes flew overhead on a flypast celebrating the occasion, with Louis and his family standing on the balcony of Buckingham Palace, taking it all in.)

At yesterday's Air Tattoo, Louis sat in a baby carriage, performed the Royal Handshake, and took a group photo with his family wearing rain jackets in the dreary weather of the day. The family were all looking forward to the trip," a royal source told People. According to The Independent, Air Tattoo is the world's largest military air show. Held at the Fairford Air Force in Gloucestershire, the event gave children a chance to see jets, helicopters, and historic aircraft.

Fans commented on Louis' behavior at the event, calling the five-year-old "the gift that keeps on giving," another fan praised his "adorable" facial expressions, and another wrote, "He always steals the show."

Louis and his brother George donned rain jackets for the gloomy weather, and the Crown Prince and Princess jokingly called it "wonderful British summer weather" (sarcasm) on Instagram. About 200,000 people attend the annual event, People reported, and while this was Charlotte and Louis' first time attending, George attended with his parents in 2016 when he was nearly three years old.

"His father had told him about helicopters, so he knew what they were and kept saying 'tail rotor,'" Flight Lieutenant Jim Hobkirk told People at the time. 'It was good to see his technical knowledge. There was training going on early."

George, Charlotte, and Louis are currently on summer break, having just finished their first year at Lambrook School, where the three enrolled together in September. The Welsh family moved from Kensington Palace in London to Adelaide Cottage in Windsor in early September, so this will be their first summer in their new home. Yesterday's surprise visit to Air Tattoo was "a meaningful excursion," People reports.
