Why will my guns on the bomber not fire online sometimes?

When your gunner can fire, the crosshairs are bright, and when the crosshairs are out of the firing cone, they go dim.

Most bombers will not let you fire below the plane, except to about 4 or 8 o'clock low. You'll notice the crosshairs go dim if they're near the elevators or rudder. A smart fighter will approach these fighters from below or above, so you can't hit them unless you abandon your bombing run to maneuver.

If you want a bomber that can fire nearly every direction, get the b-17. The BOP b-17 is more deadly than the real b-17's which had very limited ammunition, couldn't maneuver as well, and didn't have just one gunner controlling all the guns. With the b-17 you can fire almost directly below the plane via the waist gunner, you have a good field of fire in front of the plane, and above it too. The most significant blind spots are at 3 and 9 oclock.

Once you've got a b-17, you can practice against my fighter 1 on 1 if you want, in sim, as long as you fly it like a bomber instead of dogfighting. Goes for anyone - I like to practice against b-17's.
