Thanks. IT's tough to tell where bullets are coming from when attacking a buff. But I was sure once that I had swung in behind a group of LAncs and hit all three tail gunners before getting binged. Then dropped down below the wing plane hoping to get in close and kill them. But the first burst out of the buff guns took my wing off. I kept wondering "what guns can hit me from there if the tail gunners are dead." IT happened so much that I dropped the attack plan of shooting out gunners because I figured they weren't dying. 
Each bomber has a weak spot, Lancasters are in the wings, Either drop straight down or climb straight up - Dropping straight down you only face 2x 50s from the top turret, there is no ball turret.
B-24s are weak in the wings, Head on passes work quite well, or any hits on the wing set them on fire.
B-17s are a tough bird all around, head on pass works or slashing attacks.
B-29s - use slashing attacks at very high speed from the 10-11clock and 1-2 clock position, extremely heavily armed
B-26s NEVER head on this plane way to much firepower in the nose, use slashing attacks from the 10-11clock and 1-2 clock position
