Some here do argue from a very lofty point of view...
Landing message for two kills a participation medal? Hardly so.
Only about 25% of all kills are rewarded with a landing message at all. And as the kills/sortie is about 0.5 (bombers excluded) you can easily guess what a tiny fraction of sorties ends up with such a message at all. Currently we are at about 4.5 kills per player per hour (all game modes, incl. manned ack), so if ~25% result in a landing message, we end up in the area of 1 message per hour for the proverbial "average" player.
However, most messages are generated by the 'usual suspects', the small core of 'vet' players (or elite, 'top' or whatever you want to call them). So for the de facto average AH players, even landing "only" two kills is quite an achievement, three would be very rare for him. Not to speak of five.
I have the vague idea that if you raise the requirement to 5, vulching would get much more important, as for the majority of players this would be the only way to ever get their name in lights. Personally, I find the notion of raising the player skill level by such a measure quite amusing
