When her father and brother Derek started to learn to fly in 1937, Freydis insisted on the same opportunity: they all learned to fly at the
Marshall flying school in Cambridge. When the war began, Leaf volunteered as a nurse in the
Red Cross in
Colchester, Essex while trying to get into the
Air Transport Auxiliary (ATA) for over a year. She went on to work with the Aeronautical Inspection Directorate. In 1942, she joined the ATA, and began her career as a pilot. Starting with 26 hours and 10 minutes flying time, she was based in
Hamble, Hampshire. She also served in the Ferry Pools (FP) in Sherburn-in-Elmet in Yorkshire, Prestwick in Scotland and
White Waltham, in Berkshire. As an ATA pilot, Leaf learned to fly a wide range of planes from the
Vickers Wellington and the
Lockheed Hudson to the
De Havilland Mosquito and
Spitfire. By the end of the war she had 607 hours and 25 minutes flying time accumulated. Her brother was killed in action in 1944. == Post-war ==
