Sorry for late reply. I can't play the game in weekdays.
Anyway, wingman no longer crashes after take off but shows a bit risky movement. The armament was 4 Mk. 82 Snakeeye and 2 Sidewinders with filled up fuel.
Also, magical phase shift effect happens when he passes me by. So, technically, no crash occurs!!! .ini magic saves the day!!
One more thing...
I've found that F-15E cannot use ripple quantity setting when ripple interval was set to 0. The bomb drops one by one no matter how many ripple quantity was set. (of course, if we set ripple interval > 0, everything works fine.) It seems the game doesn't support simultaneous discharge of ordinances. I'm not sure why it doesn't work while jettisoning all the A-to-G equipment is possible. But if this turns out to be game engine limitation, I guess we can delete ripple interval 0 from all the aircraft.
