S!
Vulching/spawn camping/insert your word here/ is present in any game. Live with it or quit playing/change game/server/whatever if the server allows it. Personally I do not do it..if I catch a plane on ground with my bombs if the field is a target listed then it is a bonus. But staying near a hornets' nest = begging for trouble
Rather go in fast for the target and get the hell out even faster
