As part of her time representing the Royal Family, her Royal Highness the Princess of Wales embarked on a number of royal tours around the world. Often, she would fly onboard the family’s personal private jet – the royal plane.
Not only did it promise luxury and world-class comfort, but it was also headed up by some top professionals in the aviation business.
Despite this, it seems there are some unexpected things that can pose a problem for even the most skilled of pilots.
One such thing is the weather, and during one flight which Princess Diana was flying upon, an unexpected storm pushed the aircraft to plummet 10,000 feet.
Speaking on Channel 5 documentary Secrets of the Royal Flight, Bob Shields, a former navigator of the royal plane explained: “Whenever we were flying we never used the PA, the tannoy system of the aircraft because it was thought that it might interrupt a very important meeting.”

“We had left Rio in bright sunshine, beautiful weather, and according to the weather office there, it was going to be like that all day.
“So, I had sent back one of my blue cards and I had written it was going to be a fine sunny day.
“Unfortunately, on the way back from Cataratas the weather started to change and change very rapidly.”
Royal commentator, Dickie Arbiter, who was on board the flight at the time described the moment the flight dropped “10,000 feet”.
“We were heading into rotten weather and when I say rotten I mean rotten with a capital R and every other letter is capital It was chucking it down with rain,” he said.
