The Prince and Princess of Wales took their family on a tour of a C-17 transporter aircraft – the aircraft which was used to transport the late Queen's coffin in the days ahead of her funeral last September.
Eagle-eyed observers at the time spotted that the registration number of the RAF's C-17 Globemaster – ZZ177 – which flew the Queen's coffin into London, spelt LIZZ when viewed upside down.
Prince William and Princess Kate were treating their children to a day of jets, helicopters and historic planes as they enjoyed a family day out at the Royal International Air Tattoo (RIAT), one of the world's largest military air shows.
Prince George and his younger siblings, Princess Charlotte and Prince Louis, toured the RIAT with their parents as their school holidays began.
The Royals were all smiles when they arrived with the three youngsters at the air show, staged at RAF Fairford in Gloucestershire, and were greeted by Wing Commander Will Essex.
They shook hands with senior members of the RAF before the family was ushered up the huge ramp of the transport plane.
Prince George was given the chance to partially raise the ramp and could be seen pressing the button as his father watched on.
Grey skies did, however, bring heavy rain, with the RAF Battle of Britain Memorial Flight (BBMF) display and the highly anticipated aerobatic display by the Red Arrows both having to cancel their performances today.
But there were a few aircraft still in the skies before the Royals arrived.
The event was a return visit for Prince George who was taken to the show by his parents in 2016, when he was just three.
