High-level connection brigadier organised (3,6)
I believe the answer is:
air bridge
'high-level connection' is the definition.
I know nothing about this answer so I can't tell whether this works.
'brigadier organised' is the wordplay.
'organised' indicates anagramming the letters.
'brigadier' anagrammed gives 'AIR-BRIDGE'.
Can you help me to learn more?
(Other definitions for air bridge that I've seen before include "Walkway put up against plane's door" , "Link over water" , "way off plane" , "Transport link needing flying visit" , "Sky link" .)
