Flight connector? Good man taken by air! (5)
I believe the answer is:
stair
'flight connector?' is the definition.
'stair' can be an answer for 'flight' (I've seen this before). I am not sure about the 'connector?' bit.
'good man taken by air' is the wordplay.
'good man' becomes 'st' (abbreviation for saint).
'taken by' is a charade indicator (letters next to each other).
'st'+'air'='STAIR'
Can you help me to learn more?
(Other definitions for stair that I've seen before include "something of a case" , "One of a flight of steps" , "One step of a flight" , "Support on which to step" , "this could get one down" .)
