Take off where it may be possible to land (5)
I believe the answer is:
strip
'take off' is the definition.
(stripping is a kind of taking off)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for strip that I've seen before include "Remove covering from" , "Undress - maybe comic!" , "runway" , "Band; unclothe" , "Landing field - take off" .)
