​​At the School of the instructors of Tours it is the solo left on Dewoitine 500 and Dewoitine D.520. With Suzanne Melk, Elisabeth is the only one of the group to be considered capable of flying on the best plane during the campaign of France : Dewoitine D.520. She crosses successfully the tests of fighter pilot's military patent. She is patented on February 12th, 1946. ​

In May, 1947, she turns to the gliding and begins her instruction on Kranich, a two-seater German glider in the national center of Beynes placed under the leadership of Paul Lepanse, future record holder for distance. Four months later, she obtains the patent D.

Elisabeth dashes into the competition. She beats first time the feminine world record at high altitude by reaching 4 800 meters then second time in April, 1948, on a glider Meise, which she takes in 5 600 meters. During four years she practises the gliding to Beynes, Challes-les-Eaux, Saint-Auban-sur-Durance and Fayence.

Year 1952 marks a big bend in the life of the young woman. Of the aborted attempt to incorporate women into the military aviation, Elisabeth is the only one, age ten later, to emerge. The Air Force suggests her joining the squadron of presentation based to Étampes, equipped with Stampe. The acrobatic patrol that the organizer Jacques Noetinger will name 'Patrouille de France', receives ovations of the public of France and North Africa, fond of aviation meetings. She becomes the solo presenter and occurs in Morocco and in Algeria, via Spain.
