Engines are too strong and reliable.

AI is more convincing to me than ever before, but it could IMHO still use some improvement.

They still have a kind of radar where if the object is in their viewable arc out to a certain distance they will see it. At least they can't see through the airplane anymore. That was a big change back a couple of patches ago too. You can sneak up on them but it's very hard because if you appear at all in their viewable arc at any point during the approach they will see you and react.

It could be better but I don't want people to think that it hasn't improved since the earlier days. I think they can't see through clouds anymore either but I'm not 100% if that was actually implemented or not.
