Zeppelin or blimp (7)
I believe the answer is:
airship
I believe this clue is a double definition.
'zeppelin' is the first definition.
(I've seen this in another clue)
'blimp' is the second definition.
(I've seen this in another clue)
(Other definitions for airship that I've seen before include "Old flier" , "flying craft" , "Zeppelin, for example" , "Eg, Zeppelin" , "Lighter-than-air craft" .)
