![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
pods
'sci-fi escape vehicles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pods that I've seen before include "Pea-jackets" , "Groups of dolphins" , "some seals" , "From enclosed cabins" , "Seed containers" .)
