Iszi Lawrence on Diana Barnato Walker

Broadcaster and author Iszi Lawrence chooses the aviator Diana Barnato Walker. Coming from a privileged background, Diana used her pocket money to take flying lessons, flew bombers during World War II, and - aged 45 - became the first British woman to break the sound barrier. Iszi is joined by Giles Whittell, author of Spitfire Women of World War II, and Diana’s son Barney Walker.
