Aircraft seen in quiet country roads? (6)
I believe the answer is:
'aircraft' is the definition.
(I know that planes is a type of heavier-than-air craft)
'quiet country roads?' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'country roads?' becomes 'lanes' (I've seen this in another clue).
'seen in' acts as a link.
(Other definitions for planes that I've seen before include "Flat surface in Naples" , "Aircraft and tools for smoothing wood" , "Jets maybe" , "Trees" , "Those flying" .)
