Within the first two decades of powered flight, female pilots were breaking speed, endurance and altitude records. They were competing and winning against the men in air races, and women on every continent except Antarctica had begun to fly, perform in aerial shows, parachute, and even transport passengers. During World War II, women from every continent helped with war efforts, though mostly restricted from military flight, many flew in auxiliary services. In the 1950s and 1960s, women were primarily restricted to serving in support fields such as flight simulation training, air traffic control, and as flight attendants. Since the 1970s, women have been allowed to participate in military service in most countries.[citation needed]
