Experimental story: "A Golf Shot" by Spooner (5)
I believe the answer is:
pilot
'experimental' is the definition.
(synonyms)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pilot that I've seen before include "He steers ship or plane" , "One who brings a vessel into port" , "Navigator" , "Small flame that ignites a gas boiler" , "This person can be found in a plane or a boat" .)
