Take off from the hangar (4)
I believe the answer is:
shed
I believe this clue is a double definition.
'take off' is the first definition.
(thesaurus)
'the hangar' is the second definition.
(thesaurus)
'from' acts as a link.
(Other definitions for shed that I've seen before include "warehouse" , "Remove clothes in small hut" , "Small outbuilding" , "Drop - cast off" , "Get rid of - garden building" .)
