Engines are too strong and reliable.

Well overall I think such AI as it is now, is way much fun then before.
Before they were just speed junkies with bad accuracy, firing their guns allways off (unless a veteran or ace).

Even old campaigns are now way much intensive then before, and when I complete the hardest missions, I feel like I'm happy to be alive - just like reading Clostermann's or other reall ww2 pilots books. Feels intensive.
