My great grandmother had the last but one V2 land in her back garden. The impact shattered all the windows and doors but caused no structural damage even though it was only fifty yards away.
As a kid I stayed there and played in the back garden and there were holes between the trees which were in her property. Sticking out if one was a thick metal washing bowl shaped thing which I was told was part of the combustion chamber.
The were no BIG holes where the warhead would have exploded or where they would have dug for it so I presume the warhead is still down there.
The property changed hands about three years ago for £745,000.
