we discussed with some other pilot with different points of view about this point: i agree that it can be fair play to leave someone go when the engine is broken....but i don't think it's a question of honour but only of personal choice (or friendship )...because in the spirit of the game and battle you wouldn't let an enemy fly away with the chance that he is going to shoot down some of your friends the next time....plus being a tactical game you must preserve fuel and engine with some planes if you want to get out alive....then if there is bad luck and your plane is gone ...bring your parachute if i'm behind you !!! ( and i won't get offended if you do the same to me )
