As you can see in this thread so far, Pacifica, there is not one "perfect" technique, plane or ammo to get the job done, and return home safely.
Every bomber has weak points that can be exploited.
- The top gunner position in B-24's has a weak view of an attacker diving from a front, 12 o'clock high position, and only 1 set of guns per plane can be brought to bear on the attacker. A solid burst to a wing root will set them on fire. They will explode later, so pressing the attack any further on a flaming B-24 isn't necessary. Focus on flaming the remaining planes in the formation.
- Lancasters have only .303 caliber ammo in all gun positions, except rear gunner. They are vulnerable to low, front quarter attacks, again because of only one (weak ammo) gun position available to track and fire at you.
- B-17s share the sole top gun vulnerability of the B-24, but may not light up as easily.
- Ki-67s and B-26s share what I'll call a "sweet spot" attack vulnerability - a slashing attack from the side that traverses just below the track of the top gun until the last few hundred yards.
A good gunner will dispatch you quickly if you make a predictable, straight in approach across a path where multiple gun locations can track you.
You may want to tailor your attack to the prey, studying them to determine your technique, rather than using one technique against all types of bombers. Fly each of the bombers and defend yourself as a gunner, and you'll discover their weakness first hand.
And most of all... have fun and throw a out there.
