Well, flying in FE2 always brings the modding addiction out in me so I'm currently working on a mini, ver. 9.9 update of the FM pack before I tinker with my early WW2 install for SF2. Included will be the atmospherics tweaks posted above (as well as some subtle changes to clouds), also some more subtle changes to balloon explosions, for consistency, and lockout speeds will be included for control surfaces on the following early aircraft (Caudron, Taube, Longhorn, Shorthorn, HF.20, HF.20u, Pfalz E.I, MS type G 25/45/60hp, MS type H, MS L early one-seater, MS L early two-seater, Pfalz E.II, Pfalz E.III, MS type N, Fokk. E.Ia (Parabellum), Fokk. E.II (Spandau), Fokk. E.IIa (Parabellum), MS L late one-seater, MS L late two-seater). Will also include some tweaks to the AI for the Pfalz Parasol since it sometimes tries to climb too quickly, and aileron and rudder sensitivity have been further reduced on the Alb. D.II Oeffag. Should be enough for a mini-update. FM tweaks for the Snipe and some two-seaters that I've never touched on CombatAce will follow later in a bigger ver. 10.0 update.

Improved atmospherics
Improved mesh numbers and other entries in the flightengine.ini (will provide a mid-range and higher-end flightengine.ini) - these tweaks are particularly good for sightseeing and expansive vistas
More tinkering with balloon explosions
Let's not forget the observer with parachute tweak for immersion
