Aircraft from company leading the way in flying once (8)
I believe the answer is:
concorde
'aircraft' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'company leading the way in flying once' is the wordplay.
'company' becomes 'co' (abbreviation).
'leading' means one lot of letters go next to another (some letters go in front of others).
'the way' becomes 'rd' (short for road).
'in' indicates putting letters inside.
'flying' indicates anagramming the letters (letters fly around into new positions).
'once' is an anagram of 'ncoe'.
'rd' going into 'ncoe' is 'ncorde'.
'co'+'ncorde'='CONCORDE'
'from' is the link.
Can you help me to learn more?
(Other definitions for concorde that I've seen before include "Supersonic aircraft no longer in service" , "Airliner retired in 2003" , "Name of supersonic airliner" , "Supersonic airliner recently discontinued" .)
