I was rereading 'Unforgettable Weeks' and kept getting bits & pieces of a story in my mind where Andy(?) goes to England and tours the family businesses, one of which is a big military aircraft plant working on a new fighter design. Since Cantrell never wrote the follow-up, I'm obviously juxtaposing memories from another story, but I cannot remember what it was! Any idea what my feeble mind might be trying to remember?
