Song about life and extremely dangerous places to land (9)
I believe the answer is:
airfields
'places to land' is the definition.
(I've seen this before)
'song about life and extremely dangerous' is the wordplay.
'song' becomes 'air' (I've seen this before**).
'about' indicates an anagram.
'and' is a charade indicator (letters next to each other).
'extremely' means to remove the middle letters.
'dangerous' with its centre removed is 'ds'.
'life' is an anagram of 'fiel'.
'air'+'fiel'+'ds'='AIRFIELDS'
(Other definitions for airfields that I've seen before include "Where strips are" , "places to land" , "Flying bases" .)
