I would be interested in this type of mission. Although it would be nice for simpler versions without take-off to be included for escort fighters.
It's often something that is lacking in other simulations of the period. Most of the time you take off close to the bombers, climb to escort or intercept depending on the side your on without any of the strategic implications of reality. Some of those implications, though, won't be much fun when flown repeatedly I don't think.
Climbing to altitude as an escort, for example, seems to me to be sort of redundant, while the finding of the bombers using navigation or friendly ground radar would be challenging and could effect the outcome of the match. Inversely the interception forces could be spread out on several airfields even and have to form up to best overtake the bombers. They would need to start from take-off, as that is not a redundant part of the mission for them IMO.
Another key piece of this would be ground based radar, and radar guiding for the defensive force. How is that piece of the puzzle being solved by ED for the Normandy map? For me this is a very important piece, as the German fighters would have been guided by ground radar for interception and navigation.
