Božena Laglerová, the first Czech female pilot. After prematurely ending her singing career due to illness, she devoted herself to aviation. In 1911, she passed her pilot’s exam and received an International Aviation Federation license. As La Aviadora, she began performing at shows in the Czech Republic, toured Cuba and then Haiti. At the beginning of World War I, she applied to join the air force but was refused, being a woman. After the war, she married Josef Peterka, an aviation instructor and expert in photogrammetry, but she no longer flew herself and spent the rest of her life teaching singing and promoting aviation.
