Flew, or drove fast (4)
I believe the answer is:
sped
I believe this is a double definition.
'flew' is the first definition.
(I've seen this in another clue)
'drove fast' is the second definition.
(I've seen this in another clue)
(Other definitions for sped that I've seen before include "Rushed" , "Moved fast" , "Went quickly" , "got a move on" , "Hastened" .)
