Shooting and collisions are two totally different things.
Shooting works as follows:
Bob and John are in a dogfight and after a series of maneuvers, Bob manages to hit the right elevator of John's N1K2 on Bob's FE. Bob's FE knows that an MG151/20 round will destroy the right elevator of an N1K2, so Bob sees John's right elevator spin away. Bob's FE informs the server that the damage has occurred and the server then informs John's FE that his right elevator has been hit by an MG151/20 round and destroyed. John's FE then removes his N1K2-J's right elevator. This all occurs in the space of 1/4 to 1/2 of a second.
In the 1/4 to 1/2 of a second that John still has his right elevator on his FE, but not on Bob's FE, he continues to maneuver using it, his maneuvers are then sent, via the server, to Bob's FE. Even though an N1K2 missing its right elevator could not do the maneuvers that John is doing, it continues to maneuver as though it had both elevators until John's FE is informed of the loss of the right elevator, from which point John's N1K2-J follows its new flight model that lacks the right elevator.
It has to work this way because otherwise it would be nigh impossible to hit enemy aircraft. If the hits had to intersect with the target on the target's FE, the attacker would have to guess where the target was on the target's FE. If hits had to intersect with the target on both the attacker's FE and the target's FE on direct 6 o'clock and direct 12 o'clock shots would hit.
Collisions work as follows:
John, now missing his right elevator, continues to turn, hoping that his slower moving N1K2-J can still turn inside Bob's fast moving Fw190D-9 as Bob comes in for another attack. On John's FE he cuts across the path of the onrushing Fw190D-9 with about 100 yards to spare, managing to get through the line of fire without having any more systems destroyed. On Bob's FE John's move is taking place 1/4 to 1/2 of a second later. Bob sees John's break turn, slower because of the elevator damage, and dives in for the kill. Bob presses his attack too aggressively, sees a possible collision and slews his rudder over to try to pass behind John but, unfortunately for Bob, his left wing intersects with the tail of John's N1K2-J, and is ripped off. Bob tumbles down and bails, leaving a damaged, somewhat puzzled John with the victory.
Collisions have to work this way. In the example, John correctly estimated that he had room to cut in front of Bob's Fw190D-9. Bob miscalculated his maneuver and collided with John's N1K2. John should not be punished when he estimated correctly and Bob estimated incorrectly. Likewise, Bob should not be rewarded for his mistake by either destroying John in a collision or by passing through John's aircraft unscathed. Both pilots had a chance to avoid colliding with the other on their own FE, but only John was successful.
If both aircraft were destroyed when a collision occurred people would use this to their advantage. If it takes the attacker 10 minutes to get to your base and you 30 seconds to takeoff and collide with him you can be back where you were 30 seconds later but it will take your enemy 10 minutes to regain what he lost from you colliding with him in a way he could not avoid. After all, on his FE you flew across his flight path 300 yards behind him, why should he have dodged?
On the other hand, if there has to be a collision on both FEs in order to for a collision to occur, then people will simply fly straight through their targets,firing all the way (hitting from 10 feet out is easy), without worrying about colliding. After all,I know that the B-17 I am diving on is, on my target's FE, 150 yards ahead of where it is on my FE. I know there won't be a collision, but I will definitely nail him with by guns as I fly through the image of his B-17.
