. . . one taking six more into a storm flying (8)
I believe the answer is:
aviation
'flying' is the definition.
(I've seen this before)
'one taking six more into a storm' is the wordplay.
'one' becomes 'a' (**).
'taking' is a charade indicator (letters next to each other).
'six' becomes 'vi' (roman numeral).
'more' is a charade indicator (letters next to each other) (some letters added to the previous ones).
'storm' indicates anagramming the letters.
'into'+'a'='intoa'
'intoa' with letters rearranged gives 'ation'.
'a'+'vi'+'ation'='AVIATION'
(Other definitions for aviation that I've seen before include "Job; date" , "The business of flying aircraft" , "Aircraft operating business" , "Flying in general" , "Mechanical flight" .)
