Fugitive without a landing strip (6)
I believe the answer is:
runway
'landing strip' is the definition.
(I've seen this before)
'fugitive without a' is the wordplay.
'fugitive' becomes 'runaway' (synonyms).
'without' indicates named letters should be taken away.
'runaway' with 'a' taken away is 'RUNWAY'.
(Other definitions for runway that I've seen before include "Strip on which planes take off and land" , "Essential airport feature" , "Where one takes off" , "takeoff point" , "Take-off and landing strip" .)
