Legendary skydiver (6)
I believe the answer is:
icarus
'legendary skydiver' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for icarus that I've seen before include "one with disintegrating wings" , "High-flying son of Daedalus" , "Flier with wax wings" , "Greek mythical youth who flew too close to the sun" , "Mythical Greek who flew too close to the sun - oops!" .)
