I have found three examples of women in jobs that are traditionally done by men:
Women on space (like the cosmonauts Valentine Tereshkova, Rally Ride, Anousheh Ansari or Karen Nyberg); women presidents and prime ministers (like India Ganhdi and Pratibha Patil in India, Ellen Johnson in Liberia and Dalia Grybauskaite in Lithuania); and military women who are, for example, at this moment 20% only in the USA army.
