bookworm,
If someone had tried to kill me, I think I'd be annoyed, and I think I'd expect the other guy to apologise at least. Certainly if I'd inadvertantly misunderstood a simple radio call and not seen a microlight in front of me on final, I'm absolutely sure that I'd apologise.
Take a magnanimous attitude? I think you'd need to be a bloody saint to do so. And I think if it were me I'd find it far less stressful to get thoroughly and extremely annoyed. In fact, I can think of a lot of other things I might say and do to the other person to reduce the stress too...but maybe I shouldn't write them on here.
