On Tuesday, King Charles and Queen Camilla returned to the UK after completing a quick visit to Canada.
Camilla has been a staunch supporter of her husband, particularly while the king undergoes his illness treatment. However, the Queen had to face a tremendous obstacle when she joined Charles on the 20-hour journey.
According to former royal butler Grant Harrold, Camilla was terrified while traveling to Canada with the royal couple on a historic trip.
"While she has to travel all over the world, flying was never her favorite mode of transport," the former employee revealed, adding that the 77-year-old is "definitely not a fan of flying."
