I've also got a copy of the bomb damage maps, and they confirm all the V1 incidents mentioned in these posts: One Tree Hill, Bovill Road, Fermor Road/Marler road, Fairlawn and the Station/Perry Vale .

From what I have read, SE London suffered from V1 attacks because it was on the flight path from their launch bases in northern France to London and they often fell short. Don't think they were capable of being specifically targeted.

For those who want to read more, I'd particularly recommend "Red Alert" by Lewis Blake. It is a detailed account of the bombing in SE London. There are copies at all the local libraries.
