Where one finds oneself at end of flight? (8)
I believe the answer is:
upstairs
'flight?' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for upstairs that I've seen before include "Having taken steps to rise" , "See 3" , "in one's mind ..." , "On a higher floor" , "Above ground floor" .)
