Yvonne taught me to fly on a Tiger Moth in 1959. I visited her again recently and we had a lovely afternoon reminiscing about flying. She was a great instructor (kindly but demanding high standards), I am so glad she had such a good career and won so many awards. But she had to overcome a lot of male chauvinist piggery along the way.
Read her book 'Trailblazer in Flight' published by Pen & Sword Books Ltd.
