What's flown by a test pilot? (4)
I believe the answer is:
kite
'pilot?' is the definition.
(I know that kite is a kind of glide)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for kite that I've seen before include "Quadrilateral; bird" , "Bird of prey and flying toy" , "High as a - -" , "flyer" , "Flying toy or kind of hawk" .)
