you should try from the high 11 or 1 oclock (and not a collision course).. even someone like 999000 will have trouble hitting you.
My favorite is the chin attack - from near 12 oclock low, pull up for a lead shot from below, taking the shot at 70-90 climb from short range as the bomber flashes infront. With something that has plenty of cannons and good front view (mosquito VI in my case ) it is a killer. there are very few guns that can point at you from that angle and aiming for the gunner is awkward. Also, both the closure speed and disengage speeds are very high since the speed of the bomber and the fighter add up. The down side is that you can only kill one bomber and then, unless you had lots of E to begin with, you have to chase the other two and position for another attack.
All these "how easy it is to kill a bomber" theories do not work as well in MA conditions. We are not talking about a bomber formation on the way to the strats in the middle of nowhere. This thread is about bombers attacking fields and in that case the fighter do not have all the time in the world to position for an effective attack. The ranges are short and he needs to down the bombers before they drop their bombs on the target. Enemy fighters often will make the attacker turn into them and prevent convenient positioning. In those cases the fighter must press an attack or not do it at all.
More over, consider the effect of two noobs in bombers against a veteran fighter vs. two noobs in fighters/jabos against the veteran. If they arrive in jabos or fighters, the veteran will likely dispatch them both with ease and continue to kill others. If they come in bombers, and lets say they are so clueless that they do not know they can man the guns, the vet will kill all 6 of their bombers and run out of ammo. So now the vet will land 6 kills and get an 'attaboy' but two noobs have removed him from the fight, just by making him expend all his ammo into helpless bombers. They have not shot him down, but
they did send him back to the tower. Also, they kept him engaged for long minutes while he was positioning for ideal "safe" attacks - 6 times at least.
The bottom line is that inexperienced players are FAR more effective in bombers than in fighters/jabo. Generally, in shutting down fields, 5 players in 20k bombers are more effective than the same 5 players in 20k JABOs - and the absurd is that the level bombers will hit more accurately than the JABOs, without coming down into the climbing defenders and even while under attack from fighters that made it to 20k. This is what the original post was about - not survivability, I am fine with the 3 ship formations, it is about the laser precision high alt bombing. I am also fine with the ability to place a single 500 lb bomb into the open turret of a wirble/ostie from 10k - it is just that accuracy should deteriorate with alt.
