Stephens joined the 27th (Gloucester) company of the WAAF when it was formed in 1939, becoming its first commanding officer. During the
Second World War Stephens served in Britain, Belgium, and Germany, and was the second member of the WAAF to cross the channel after
D-Day. After the war she continued to serve in the WAAF, which in 1949 became the
Women's Royal Air Force (WRAF). In 1950 she took charge of the WRAF training depot at
RAF Hawkinge, becoming the first woman to run an RAF station. In 1951 she was promoted to
Group Officer; from 1952 to 1954 she was Inspector of the WRAF, and, from 1954 to 1957, its deputy director under
Dame Henrietta Barnett. She spent two years in Germany with the 2nd Tactical Air Force and in 1960 was appointed Director of the WRAF and an Honorary Aide de Camp to Queen Elizabeth II, with the rank of
Air Commandant, on Barnett's retirement. She held this post until she retired in 1963, when she was succeeded by Dame
Jean Conan Doyle. ==Later life==
