Stories about international airmen (6)
I believe the answer is:
pilots
'airmen' is the definition.
(pilot is a kind of airman)
'stories about international' is the wordplay.
'stories' becomes 'plots' (plot is a kind of story).
'about' is an insertion indicator.
'international' becomes 'i' (abbreviation eg in IMF).
'plots' going around 'i' is 'PILOTS'.
(Other definitions for pilots that I've seen before include "People who guide ships going into or out of a harbour" , "Aircraft operators" , "Shepherds" , "They operate aircraft" , "Airmen" .)
