How old was Amelia Earhart when she rode in an airplane for the first time?

Consult the Amelia Earhart Birthplace museum. They have a replica of this home-made amusement which probably could have been patented as a portative Carnival attraction. She would have been in her teens. Sister Muriel (pidge) collaborated on this project. Againthere is a replica at the museum. A neat improvised amusement device that could have been patented and maybe sold to, say A Major carnival chain.
