Amelia Earhart's (1897-1937) childhood was not the typical girl’s. She liked nothing better than to explore the banks of the Missouri River, where she climbed trees and hunted rats with her rifle (步枪). She also built her own roller coaster(过山车 ).

The exciting life of the American aviation (航空)pioneer is dramatized in the movie Amelia, which is due to come out on October 23.

After Earhart paid a pilot $1 to take her up for a short fly in his plane, aviation became her love and career.

As she later explained, “Never do things others can do and will do, if there are things others cannot do or will not do.”

Earhart found herself a flying teacher and started to learn to fly. She took all sorts of jobs to pay for the lessons and to buy a second-hand plane on her 24th birthday.

In 1932, Earhart flew solo across the Atlantic. She became the first woman to make the solo crossing. She also made a flying suit for women and went on to design other clothes for women who led active lives. “Now and then women should do for themselves what men have already done —— occasionally what men have not done ——thereby establishing themselves as persons, and perhaps encouraging other women toward greater independence of thought and action.” she said.

When she was nearly 40, Earhart was ready for a final challenge—to be the first woman to fly around the world. However, in mid-flight, she and her navigator (导航员) disappeared in bad weather.

Earhart will be forever remembered as a brave pioneer for both aviation and for women.
