I generally very much like the air changes, since they bring vanilla closer to what I have been wrangling out for the Waltzing Matilda mod

, despite the fact that I'll ahve to rework some stuff to fit in due course... I do have a couple of questions and suggestions, though:
1) Excess thrust is moving to add AGL rather than speed - excellent, and much closer to reality. I assume the limitation of Thrust>Weight to get airborne will remain? The old version did, however, permit mission-specific speed changes, and no other mechanism allowed this; will max_speed multiplier be something we can add to mission stats, now (please)?
2) Turrets in vanilla don't seem to have a defence effect; splitting the effects of turrets to add both defence and attack is both realistic (it's why they were called "defensive weapons") and acts to make turret fighters a bit less attractive - fighters tend to need attack more than defence.
3) Are the effects of speed mission-affected? Bombers outpacing fighters was a huge thing (becuase if you can run faster than the fighters, then agility and firepower are pretty academic), but fighters against fighters the speed was less of a factor because both sides usually wanted a fight.
4) Any chance of specific anti-submarine values for aircraft weapons?
