Crashed fighter being transported (7)
I believe the answer is:
freight
'being transported' is the definition.
I can't judge whether this definition defines the answer.
'crashed fighter' is the wordplay.
'crashed' indicates an anagram.
'fighter' anagrammed gives 'FREIGHT'.
Can you help me to learn more?
(Other definitions for freight that I've seen before include "Cargo, goods transported" , "Something carried" , "Commercial transport" , "Consignment" , "that's carried by rail and road" .)
