I patched straight from 4.10 to 4.11 and I have no problems. i'd read where it wasn't necessary to
to do the 4.10.1 patch prior to 4.11. So that's the way mine worked. Just be sure to do the 'Hotfix'
patch though. I've also had the environment without the plane but that was due to my not having
the aircraft in my setup to fly, but usually it was bombers... But do as Guns recommends for efficient
flying enjoyment.
