Hot-tempered person in an aeroplane (8)
I believe the answer is:
spitfire
'hot-tempered person' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
(Other definitions for spitfire that I've seen before include "Hot-tempered person or British plane in WW2" , "WW2 fighter aircraft" , "Fierce-tempered person" , "Wartime fighter aircraft" , "Famous WW2 fighter" .)
