Heinkels of steel?

I'm not arguing for or against what you say, I'm just saying what I know.

Also I'm only talking about RL, I have no idea what the internal stucture of the 109 in CoD is.

As for wing vibration, a movement of 1 degree would have a noticeable effect at 150m.

In RL if you parked on a bombers six trying to make a big hole you'd end up dead. I don't know where you got the info that bullets can have 'minimal' tumble. As soon as the bullet is knocked of off its axis it will tumble, drag sees to that. A tumbling AP round is still bad news, but it's not AP anymore.

There is however still the chance that an AP round could get through the pilots armour from behind, it happened. In theory you could saw the back off a bomber with .303s, in practice it just didn't happen very often.
I've never read of it happening.
