Airport staff dreadfully rude? Wrong, when keeping cool head (6,4)
I believe the answer is:
ground crew
'dreadfully rude? wrong when keeping cool head' is the definition.
I can't judge whether this defines the answer.
'airport staff' is the wordplay.
'airport' becomes 'ground' (I can't justify this - if you can you should believe this answer much more).
'staff' becomes 'crew' (I've seen this before).
'ground'+'crew'='GROUND CREW'
Can you help me to learn more?
(Other definitions for ground crew that I've seen before include "Maintenance men" , "Team of mechanics" .)
