Girl Ed harassed in aircraft without a sound? (6)
I believe the answer is:
glider
'aircraft without a sound?' is the definition.
'girl ed harassed' is the wordplay.
'harassed' indicates an anagram.
'girl'+'ed'='girled'
'girled' is an anagram of 'GLIDER'.
'in' acts as a link.
(Other definitions for glider that I've seen before include "Plane without an engine" , "quiet flier" , "Aircraft supported solely by air" , "Girdle for silent flier" , "Unpowered aircraft" .)
