Princess Kate and Prince William are “relaxed” as their son, Prince George, has started flying lessons aged 11.

The future King ­is understood to have enjoyed his first flight last week on the final day of his school holidays.

An onlooker at the Berkshire airfield said: “He loved it. It’s the right time to start.”

The Prince and Princess of Wales watched their son soar into the air and come back to land safely just under an hour later.

The treat came on the final day of George’s school summer holiday last week.

An onlooker told The Sun: “George is only 11 years old but it is the right time to start.

“The Royal Family has a proud tradition of flying and it looks like George is next in line.

“His parents watched George take flight from the safety of the ground but he flew with an instructor and loved it.”

William and Kate, both 42, had turned up in a three-car convoy at White Waltham Airfield near Maidenhead, Berks, a 20-minute drive from their Windsor home.

George’s late great-grandfather, Prince Philip, trained at the same airfield.

Prince William is a trained helicopter pilot who has flown for RAF Search and Rescue and East Anglia Air Ambulance.

William, Kate and George also relaxed at the airfield’s teeming clubhouse, home to the West London Aero Club.

One person at the airfield told the publication: “There were probably 30 or 40 people in the clubhouse.

“Catherine and William watched George take off.

“But they were relaxed about it. All three of them had been pretty chilled in the clubhouse.”

King Charles handed over the role of colonel-in-chief of the Army Air Corps to William in May. The monarch said at the time: “The great thing is he’s a very good pilot indeed.”
