Crockery may be flying! (6)
I believe the answer is:
saucer
I believe this is a double definition.
'crockery' is the first definition.
(saucer is a kind of crockery)
'may be flying' is the second definition.
(flying saucer)
(Other definitions for saucer that I've seen before include "Cup's partner?" , "flying, perhaps?" , "If flying, it would have alien pilots" , "Piece of tableware, goes with cup" , "less than a plate?" .)
