Sci-fi escape vehicle (3)
I believe the answer is:
pod
'sci-fi escape vehicle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pod that I've seen before include "Peas grow in one" , "Fruit of a legume" , "Seed container" , "Seed holder" , "Seed case; whale herd" .)
