You must correctly identify the featured aircraft to get the correct set of coordinates. Type in the correct name of the aircraft. Four choices are listed. One of them is the correct one.
This aircraft ("jeune fille" = young girl) was a series of aircraft built in France. They were light-weight monoplanes with a wire-braced wing mounted above an open-framework fuselage built from bamboo. The pilot's seat was below the wing and between the main wheels of the undercarriage. The rear end of the boom carried a tailwheel and a cruciform tail.
