Georgia twice runs home pioneering flyer (7)
I believe the answer is:
gagarin
'pioneering flyer' is the definition.
I can't judge whether this defines the answer.
'georgia twice runs home' is the wordplay.
'georgia twice' can mean two substitutions for 'georgia'.
'georgia' becomes 'GA' (abbreviation for the US state).
'georgia' becomes 'GA' (abbreviation for the US state).
'runs' becomes 'r' (cricket abbreviation).
'home' becomes 'in' ('he's home' can mean 'he's in').
'ga'+'ga'+'r'+'in'='GAGARIN'
Can you help me to learn more?
(Other definitions for gagarin that I've seen before include "Astronaut" , "Yuri --, cosmonaut" , "Yuri ......, first Russian into space" , "circumnavigator" , "Yuri --, space pioneer" .)
