He flew too close to the sun (6)
I believe the answer is:
icarus
'he flew too close to the sun' 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 whose wings melted" , "he drowned" , "Ill-fated son of Daedalus" , "Legendary character" , "one on hazardous trip" .)
