Ok, let me post somtething. I've had A LOT to drink, but it doesn't stop me fromt posting wisdom.
When attacking a fighter, you trade speed for surprise. You attack from the sun, from the clouds, from below 6'oclock, etc. You set up your path and prepare to get within 400 yards for that convergance sweet spot.
When attacking a bomber, you trade surprise for speed. The problem with bombers is that they are either lining up their shot (taking away the position of gunner) or trying to line on a fighter going at 500mph + (if possible). You can't surprise a bomber, you need to attack it in the spots where it is its weakest. Like: Beam, Flank, 12'o'clock, and straight from above. It is your own dang fault for being shot down by the combined firepower of 3 bombers. Attack from a position where you are vulnerable and you deserve to die. Dead-on six attacks are suicide, remember, the closing rate is the bomer's speed minus your speed, which can result in easy kills for the bomber. Study your target, study its turrets, study its arcs, and attack from positions of superiority. To do so otherwise is the mark of a impatient and amatuer pilot.
