Where audience can't see what pilot wears? (5)
I believe the answer is:
wings
I believe this clue is a double definition.
'where audience can't see' is the first definition.
(I've seen this before)
'what pilot wears?' is the second definition.
(I've seen this before)
(Other definitions for wings that I've seen before include "where audience can't see" , "Award at end of pilot's course" , "theatrical part" , "Sidelined player's" , "What pilot wears" .)
