Land or crash the plane (5)
I believe the answer is:
nepal
'land' is the definition.
(Nepal is an example)
'crash the plane' is the wordplay.
'crash' is an anagram indicator.
'plane' with letters rearranged gives 'NEPAL'.
'or' acts as a link.
(Other definitions for nepal that I've seen before include "mountainous area" , "Mountainous country" , "hilly part of Asia" , "place in the mountains ..." , "mountainous region" .)
