Aussies missing flight found in Science Museum (4)
I believe the answer is:
emus
'aussies missing flight' is the definition.
I can't judge whether this definition defines the answer.
'in science museum' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EMUS' is hidden in the letters of 'science museum'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for emus that I've seen before include "Largest native Australian birds" , "laboratory units" , "Muse about flightless Australian birds" , "Aussie birds" , "Fast, but not high-fliers" .)
