Surname of the first woman to fly solo across the Atlantic (7)
I believe the answer is:
earhart
(Other definitions for earhart that I've seen before include "Amelia --, first woman to fly the Atlantic" , "Amelia ......, American pioneer aviator" , "Amelia __ , aviator, d. 1937" , "Amelia . . . . . . . , pioneer aviatrix" , "high-flier" .)
