'flight' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?

'returned wine second-rate one found on' is the wordplay.
'returned' shows that the letters should be reversed in order.
'wine' becomes 'retsina' (type of Greek wine).
'second rate' becomes 'b'.
'one found on' is a charade indicator (letters next to each other).
'retsina' in reverse letter order is 'anister'.
'anister' after 'b' is 'BANISTER'.
