A curse from this UFO? (6,6)

Ross

I believe the answer is:

flying saucer

I'm a little stuck... Click here to teach me more about this clue!

'this ufo?' is the definition.
('flying saucer' can be a synonym of 'ufo')

'a curse from' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
an anagram of 'curse' is 'sucer' which is present in the remaining letters.
'from' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for flying saucer that I've seen before include "UFO?" , "Phenomenon" , "observed when bull enters china shop?" , "Extraterrestrial visitor" .)
