Country where plane crashed! (5)
I believe the answer is:
nepal
'country' is the definition.
(I know that Nepal is a country)
'plane crashed' is the wordplay.
'crashed' indicates an anagram.
'plane' anagrammed gives 'NEPAL'.
'where' is the link.
(Other definitions for nepal that I've seen before include "Asian country, capital Kathmandu" , "Hindu kingdom in south Asia" , "Asian kingdom" , "Mountainous country" , "hilly part of Asia" .)
