Aircraft industry's mishandled privatisation; exotic trips excluded (8)
I believe the answer is:
aviation
'aircraft' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for aviation that I've seen before include "Aircraft operating business" , "The aircraft industry" , "Job; date" , "The business of flying aircraft" , "The practice or science of flying aircraft" .)
