Since I'm having some trouble tracking down a couple of new leads, I thought I'd post a bit of information I have on one of the memorials I'm looking for: Hainford, Norfolk.
Hainford is the site of the Hookem Cow crash on 14 April 1945. She was a B24, flying out of Horsham St Faith. She has her own website, where you can find loads of information:
I have found the gravesites of the boys who died in the crash, and they can be found here:
And here is a photo, from hookemcow.com, of the memorial at the crash site. I'm trying to track down the location, but have had no joy as yet. A couple of leads, but nothing substantial.
