Also stuck on 2 single missions...

[Zegroh]

Hi,

I'm stuck on the mission 'defend a friendly' in the battle of britain. I can't seem to keep the friendly alive. Even when I shoot down all the enemies, the friendly still crashes eventually on his own. What am I missing here?

Second mission: 'Downtown Berlin' in the battle of Berlin. Well uh, yeah the fighters shoot down all my bombers within the first 2 minutes or something. Any tips here? I really don't know how to get trough this one.

Any help is appreciated! Thx!
