Carol Vorderman, 58, was taught by pilot Emily Collett, 36, to perform a loop-the-loop back in July 2017.
The Countdown legend offered her condolences in a tribute post on the micro-blogging site where she retweeted an article following her death.
In view of her 411,000 followers, she captioned the post: “Such a terrible terrible loss…Emily was an extraordinary young woman and pilot and my time with her in the air was nothing but a joy.
“My heart goes out to her husband Mike, to Emily’s family and to Tom Castle’s family in their grief. Rest In Peace.”
