A few people have said stuff about bombing at 20 - 30k up and how no one has the temperment for it.
Aside from my low level DB and porking raids, I usually find myself bombing from AT LEAST 20k. If the map has a good visibility I go higher. Most players dont have the temperment to take their fighters up there to stop you at 20 - 30k and the ones who do get my respect because they actually take the time, select the RIGHT plane and then commit to it (Aside from the random 163 pilots who just light the rocket, pull up and take potshots).
Hitting an enemy HQ or base from 30k is fun. They cant even see you at that height so the explosions just happen out of no where. Sure they get the flashing base but they dunno whats making it flash aside from something in the air that they cant see in the dar ring.
