An airplane should never survive hitting a tank regardless of the tank's surviving.
Because you obviously have no idea how the collision model works in this game, maybe this will clue you in.
CollisionsCollisions and how they are modeled is one of the most misunderstood, and therefore most contentious, issues in the game. The usual question is how 1 player can suffer catastrophic damage in a collision while the other player suffers no damage at all. The explanation is in the understanding of how lag affects the reality on the two front-ends and how HiTech mitigates collisions.
The first thing you must understand is that a collision can occur on one front-end but not on the other. The reason for this is the different realities caused by lag. Player 1 can see himself safely past Player 2 at point A while at exactly the same time Player 2 sees himself colliding with Player 1 at point B. Whether through maneuvering to avoid the collision or just plain luck, Player 1 did not collide on his front-end. Player 2 did.
Since a picture is worth a thousand words, take a look at the images below. They are from films of a duel between Bronk and Tangle. The first picture is from Bronk's film and clearly shows Bronk colliding with Tangle.
The second picture is from Tangle's film and shows Tangle's view at exactly the same instant. Notice the "Bronk has collided with you" message in the text buffer. In Tangle's view, though, there is almost two plane lengths of separation between him and Bronk.
The second key to understanding collisions is knowing how HiTech mitigates collisions. It's really very simple: If a collision occurs on your front-end, you suffer damage from the collision. If a collision does not occur on your front-end, you do not suffer damage. Looking at the two images above, it is pretty clear that this is the only way to do it. How would you like to be Tangle in this scenario and receive damage from a collision you were obviously not involved in?
There are lots of scenarios where a collision can occur on 1 front-end and not the other. You may not even see the collision (i.e. you were looking a different direction) and suddenly suffer collision damage. You may see the collision, but the other guy maneuvered out of the way. The bottom line, though, is in your front-end's version of reality, a collision occurred. If a collision did not occur on the other front-end's version of reality, the other player's plane will not suffer damage.
