In Greek mythology, a son of Daedalus who flew too near the sun when trying to escape from Crete (6)
I believe the answer is:
icarus
(Other definitions for icarus that I've seen before include "In Greek legend, he flew too high and died" , "Daedalus's son" , "Son of Daedalus, who flew too close to the sun" , "One who flew too close to the sun" , "made a dangerous flight" .)
