The last but one V2 landed in my great grandmother's back garden. The impact blew all the windows in and half the tiles off the roof but the warhead didn't go off so the house stayed upright. Five years later there were still a couple of holes in the ground with bits of the combustion chamber. Because the warhead hadn't gone off the surrounding trees were unaffected.
Rumour has it that the warhead was down far too deep and dangerous to recover safely so they left it there.
I must wander around there one day and tell the present owners, who paid something like £485.000 for the property, my concerns.
