OK...
Let's brake it down to you in as a simple way as possible WindX.
Aces High colission and gunnery system for Dummies: By Wilbus
What you see on YOUR screen is what happens and it registrered.
When you fire your guns and hit the nmy plane THAT is what is registrered to the server then to the NMY plane and he hears the hits EVEN if he for some reason (massive internet delay) is BEHIND YOU. This is why people who happen to warp sometimes kill you from 2000 yards away, they see you sitting in the air, fire and then if they happen to get their connection back those hits are registered to you.
Colission system works the same way. What YOU see is what happens. IF You fly into an nmy plane YOU collide in him, doesn't matter if "he" bares the responsibility (IMO of course) (say he pulls around hard to avoid your attack, you hit his plane on your screen). When YOU hit HIS plane on YOUR screen he may infact be 50 yards away from YOU on HIS screen.
This is WHY COLISSIONS and RAMMING on purpose is virtually IMPOSSIBLE.
In order to actually ram someone on purpose you would have to have really low ping times, both of you, probarly have to play over LAN. This is also the reason usually only one guy goes down in the collisions.
As for AKAK photoshopping the picture... why would he have to?
I've flown both with and against him and he's good enough to not have to do this, specially not when faced vs newbies.
Do this. Tell AKAK to Duel you in the DA. All Fair game, plane of choice, 25% fuel, best out of 5 fights (can change planes after every fight). Film it and put it up on the BBS.
