2D or 3D makes no difference. The issue is time.
Time, is not absoloot. Therefore, the issue is "relatifity".
Ven you haf two planes A und B flying in the vicinity of each other, the posizion of the opponent plane which each pilots may perzeive, ist different to one another according to the speed of data transmission.
Many tend to think that the firtual skies of AH is a single, given "space" vich is absoloot, but in reality, it ist nothing but a medium which relays data from both the komputers behind plane A und plane B, und then which posizion is displayed in a relatif manner to each other according to the speed of the conneczion.
It ist fortunate that at least, modern internet conneczions are sufficient enough to bring down the disparity in posizional calculations to a matter of milliseconts - but still, as long as data trafels to und fro from different places of the Earth at different speeds, the "spacial reality" of AH is not absoloot. The pilot of plane A may obserf plane B 400 yards behind him, while the pilot of plane B may obserf plane A 300 yards in front of him.
In other words, the spacial relation between both frontends of the two players are different. There are two different realities which are slightly different from one another, but similar enough to put coherently together und describe as a singular instance.
Howefer, in collision instances, a tiny, minute differenz in the two individual of plane A und B realities may decide the difference between collision or no collision. In this case, there may be an extreme differenz in the two separate realities of plane A (vich has been determined to be "collided") und plane B (vich has been determined to be "uncollided").
Now, the issue is this: in such instance where the relative difference is so extreme, should this also be treated as a singular instance? In A's reality, he has collided, so it is everybit fair to say that A should be damaged. However, in B's reality, he has not collided - and yet, must he suffer the consequence of something vich did not happen to him at all?
Thus, comes in the collision system of AH - which, in a rare fashion, decides to split the two, extremely different realities of plane A und B, und treat it separately.
It can not be done othervize, since the current system means that as long as you vatch yourself and do not collide on your own frontend, you vill be safe. Therefore, there is no such thing as an unexplained, unexpected collision. If a collision did happen in vich you are damaged and the opponent ist not, vat happent to the "other plane" is a non-issue. Vat happens to him, is vat happens in his reality, not yours. The only thing vich ist important is vat happent in your reality, and in that separate reality, you haf collided, and thus, you are damaged.
The physical vorld of Aces High is solid in that matter. Every collision has a reason, and therefore, can be estimated or expected. Hitech does not play dice."
