Ok so I'll bite, based on the OP, how is a single pass head on firing on each other not a HO?
My apologies to everyone who has proposed a question or a comment. I will address them all, but due to my limited time I have to prioritize according to questions that I think reflect the silent majority that are too intimidated by the awesomeness of this suggstion to comment. Therefore, I will address Gyrene's question above second. My first answer goes to Waystin - yes, I'm serious.
The following is my answer to Gyrene's and the silent, intimidated majority's question:
A joust is not a HO and that is what people don't understand and it is yet another injustice that this arena will help to correct.
A joust requires one to vector his/her aircraft in the direction of the opponent whilst manuvering to critically wound the opponent with his/her guns at the same time placing his/her aircraft in the path of the velocity vector of the opponent's aircraft but hopefully not placing himself on a collision course with the velocity vector of the opponent's bullets. A HO is a manuever that places the opponents plane in the path of the attacker's plane for a killshot whilst positioning oneself in harms way (hopefully not - but maybe) regardless of velocity vector of the opponent's plane or bullets and the collision course they may be on with the attacker's plane.
Capice?
Discuss.
