Order airborne -- dare pilot to break record held (11)
I believe the answer is:
lepidoptera
'order airborne' is the definition.
(I've seen this before)
'dare pilot to break record held' is the wordplay.
'to break' indicates anagramming the letters.
'record' becomes 'ep'.
'held' is an insertion indicator.
'dare'+'pilot'='darepilot'
'darepilot' is an anagram of 'lidoptera'.
'lidoptera' going around 'ep' is 'LEPIDOPTERA'.
(Other definitions for lepidoptera that I've seen before include "Order airborne" , "Class of insects" , "Tepid or pale (anag) -- butterflies and moths" , "butterflies, perhaps" , "Order of the Peacock" .)
