Thing managed to escape in dark voyage (5,6)

I believe the answer is:

night flight

'dark voyage' is the definition.

'thing managed to escape' is the wordplay.
'managed' is an anagram indicator.
'to escape' becomes 'flight' ('flight' can be a synonym of 'escape'**).
'thing' with letters rearranged gives 'night'.
'night'+'flight'='NIGHT FLIGHT'

'in' acts as a link.

I've seen this clue in The Mirror.
