Technically a HO is when all two planes are shooting face to face. But what if (like INK said), when two planes are going towards each other, one breaks to avoid, kick rudder etc, and the other one is making the pass on him? Then extends, returns and plays the same game again and again? In my dictionary thats the lowest behaviour ever. Unfortunately there are many out there from those and they are real hard to avoid if they are in the fastest rides. The only case i HO when i meet one of those and i get real pissed after 8-10 passes. Thats all for the HO, everyone has his own opinion. I ask all of you NOT to do it. End of hijack.
