Female Helicopter pilots ......
Whirly Girl history shows that Dini Petty was born in the UK and became WG 131. Think this was in 1967 at age 22. She was a TV Personality and flew her pink H269 doing traffic patrols in Toronto, Canada. Very experienced and highly regarded. Believe she was born in 1945 and at 70 was/is still flying. Google shows some great photos. Maybe this is on interest.
Australia had first Whirly Girl in 1965 (No.99), second was No.248 and third was No.332. Not sure if any in between but had a highly experienced No.530. The numbers signify order in which their helicopter pilot licences were attained. Originally the group was formed for the first 100 in the World, but has grown somewhat since. Hanna Reitsch was WG No.1 and is reported to have been the first pilot to fly the first practical helicopter, in the World.
