No, point of fact the allies spread out away from the areas they had to defend, crossed the channel, and orbited over airfields in France to pick off cheap kills.
This isn't war, it's a wargame (more so than the MAs anyway) and part of the FSO has been an atmosphere of good sport, good characters.
You note we don't allow chutes to go around killing planes on the runway with their pistol? You'll note the objectives are never bloody deathmatches with "last man standing" mentality, but rather focus on semi-realistic war goals (defend this, attack that, etc). Vulching doesn't have much place in here, unless it's literally in the middle of combat, under a giant furball that happens to be over the field in question.
This was the end of the frame, planes should have been RTB. Instead they were across the channel from their likely defense area, vulching the few that managed to escape the slaughter-fest over Britain. Allies had their fair share of kills, they didn't need a few more. Seems rather poor sport and dishonorable.
EDIT: I know it's over and done with. It's old news. But folks glossing it over like it's a good thing doesn't sit well with me, so I wanted to clarify what was going on, give you a better picture.
