Jean Batten was a famous aviator (pilot) who was born in Rotorua, New Zealand in 1909. In the 1930's she made several record-breaking solo flights (on her own) across the world. In fact, she was the first person to fly solo from England to New Zealand - a huge achievement! She also flew a number of long solo flights between England and Australia/Brazil. When she flew, she always took a silk dress with her so that she could look beautiful at the parties she attended upon her arrival.
Amelia Earhart was an American aviator who lived at about the same time as Jean Batten. Like Jean, she also flew solo. In fact, she was the first female aviator to fly solo across the Atlantic Ocean. She flew all the way from Canada to Northern Ireland on her own without stopping. In 1937, Amelia Earhart attempted to circumnavigate (go right around) the world. Unfortunately, the flight ended in tragedy when she disappeared near Holland Island, about halfway between Australia and Hawaii. She was never found.
Here is what I think the difference between these two.
Jean was famous and she flew to country to country. She made record breaking solo flights. She was born in Rotorua.
Amelia flew across Country's and the sea. And she was the first ever female to fly across the Alantic ocean. But when she tried to fly across the world she disappeared.
