Detective flying our helicopter (7,6)
I believe the answer is:
hercule poirot
'detective' is the definition.
(I've seen this before)
'flying our helicopter' is the wordplay.
'flying' indicates anagramming the letters.
'our'+'helicopter'='ourhelicopter'
'ourhelicopter' is an anagram of 'HERCULE POIROT'.
(Other definitions for hercule poirot that I've seen before include "Agatha Christie's detective" , "Fabled detective" , "Christie's Belgian sleuth" , "Fictional Belgian detective" .)
