Where feathers used to fly and pilots still do (7)
I believe the answer is:
cockpit
This clue could be a double definition.
'where feathers used to fly and pilots' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'still do' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for cockpit that I've seen before include "Navigation room" , "Driver's compartment in a racing car" , "Air pilot's compartment" , "Frequent battleground" , "Where fights take place" .)
