High speed flier? (3)
I believe the answer is:
bat
This clue might be a double definition.
'high' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'speed flier?' is the second definition.
'bat' can be an answer for 'speed' (thesaurus). I'm unsure of the 'flier?' bit.
Can you help me to learn more?
(Other definitions for bat that I've seen before include "Wooden implement for cricket" , "Small flying mammal - like 11 Across" , "Night-flyer" , "Flutter (eyelids)" , "Nocturnal flier" .)
