One problem I face alot is how to react in a bomber against enemy fighters or flak, one thing you should remember is when you face bandits (I.E. fighters) you should try to spread out your formation in order to keep the fighters from hitting one plane then imidiatly moving to the next, where as when it comes to SPAAA fire (I.E. Self Propeled Anti Aircraft Artillery A.K.A. Flak you know the stuff that goes boom in the skies like fireworks) you should try to close in your formation so you have mutual protection from the schrapnel coming from the AAA (you know so you don't end up like the guys in the picture).
