http://www.bombs-away.net/ Has a long list of mirror sites. It's somein like 25MB. I haven't bothered to download it yet, some people are having problems... others aren't. Problems with the AI and such not being able to run the "engine management" properly (engines blow out if you run too hot apparently).
The big thing with this patch is the engine management, and damage to engines will reduce power output... so if you don't fly the bombers in the first place then it may not be worth the download if you don't have any lockups or CTDs right now.
FM for the fighters hasn't been touched, so they are still the bogus easy-mode Me-163 Komets.
