"I don't know how much influence a script writer has in a production ..."
In general, very little.
That is, unless that writer happens to hold the "option" to the material being produced -- which I do. That makes me producer as well as writer, which means I get to have some "say" in how this goes down. I've promised Tuck's family that I'd tell his story in a way that honors his memory as well as others like him. Doing it this way gives me the best chance of keeping my promise.
"I think you are among like-minded folk on this Forum and I hope that they listen to you."
It's likely I who will listen to them. From what I've seen here thus far, most everyone here almost certainly knows more about the Battle of Britain participants, events and hardware than I. I'm truly glad I found this site.
And Tempest, your comment about posting this information to the Battle of Britain Historical Society forum did not go unnoticed, and is greatly appreciated.
