Crews hit out after pressure from Glasgow airport (9)
I believe the answer is:
prestwich
'glasgow airport' is the definition.
(airport near Glasgow)
'crews hit out after pressure' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'after' is a charade indicator (letters next to each other).
'pressure' becomes 'p' (abbreviation).
'crews'+'hit'='crewshit'
'crewshit' with letters rearranged gives 'restwich'.
'restwich' after 'p' is 'PRESTWICH'.
'from' acts as a link.
(Other definitions for prestwich that I've seen before include "town near 29 [MANCHESTER]" , "Northern town" .)
