I read this book a few years ago and it stuck in my head as a potential Bag the Hun scenario project, although how it could actually work has been a bit of a sticking point too, to say the least. After some thought, I've come up with a potential solution, which is to develop a solo scenario system based partially on the Bag the Doodlebug V2 interception mechanisms in the Bag the Hun rule book. In this variant, the German aircraft would be controlled by the system, while the player would fly the Hurricane to launch, intercept, bail out or ditch then be picked up by the convoy escort.
The focus would be on intercepting the Fw-200 Condor, BV-138 and Ju-88 long range aircraft that shadowed convoys, rather than convoy protection against waves of torpedo bombers. There's no reason that the latter couldn't also be included in a set of scenarios but it wouldn't fit with the solo focus of the game. and would require a full convoy of shipping. It's a minimal outlay project as a result, requiring a handful of Tumbling Dive models, with all of the required aircraft already available in the 1/600th Vapour Trails range. I'll give this some more thought and see what I can work up.
