All those other threads where folks claim "they know how to ram" or know that folks purposely rammed them is nothing but bs.
Actually it isn't BS, although you're correct in that the FE that detects the collision is the person who gets killed from it. What you have to be able to do is guess the lag and put your plane where it hits them on their FE. Not easy by any means (far easier to just shoot em), but not impossible either. The worst part about it is, if done properly, you kill the other guy and get away scott free.
If you actually DO hit them, chances are he won't die because his FE won't see the collision.
Trying to use this offensively on purpose is gamey and pathetic. I wouldn't call it cheating per se, but it's not far removed.
