Digging up a very old thread here, but I’m interested to hear the story you have on the capture at Hucknall. Henry Andrew Boniface is a relative of mine, I don’t really remember the story, but do remember being told it wasn’t exactly as depicted in the film with regards to the actual capture on the runway with the gun. I don’t remember hearing him being on xmas leave, but I would have heard this story as a child, so its been a while.

I do have stored somewhere documents showing Henry providing details to the books author, and I have the postcard Franz von Werra sent him when he reached New York. I understand he sent postcards to others he met along the way as well? but I’ve yet to find a copy of any, I have a vague memory of the book having one in it? but I don’t have any of this stuff to hand currently.

Heres a picture of the postcard via Hucknall flight test museum: https://twitter.com/huftm1916/status/1237282483919609857?lang=en
