Airmen forced to stay (6)
I believe the answer is:
remain
'stay' is the definition.
(I know that stay can be written as remain)
'airmen forced' is the wordplay.
'forced' is an anagram indicator.
'airmen' with letters rearranged gives 'REMAIN'.
'to' is the link.
(Other definitions for remain that I've seen before include "Stay (in position)" , "Marine (anag)" , "Airmen (anag.)" , "Old dance" , "Stay around" .)
