Report of missile going over home (8)
I believe the answer is:
bulletin
'report' is the definition.
(I know that bulletin is a type of report)
'missile going over home' is the wordplay.
'missile' becomes 'bullet' (bullet is a kind of missile).
'going over' means one lot of letters go next to another.
'home' becomes 'in' ('he's home' can mean 'he's in').
'bullet'+'in'='BULLETIN'
'of' acts as a link.
(Other definitions for bulletin that I've seen before include "Brief report issued to the public" , "Official statement for publication" , "Broadcast summary of news" , "Regular report" , "Regular newsletter" .)
