Land or crash the plane (5)
'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".)
