The original off and HIR both have rediculous AI and it is very hard to fly any length of time with out getting shot out of the sky.
At lest in ROF when I make myself industructable I can fly for a while without getting shot up immediatly. That absolutly ruins oFF for me. I am sure i will not waste my money om WOFFUE as i can not imagiane they have improved the AI that much.
Although I've never tried it I believe that you can accomplish immortality in WOFF UE. And I think that comparable settings were available in OFF and HITR too.
Go to workshop/more settings and make the following selections:
outcomes - easy, pilot never dies
invincible - on
rear guns - less accurate
You can also set main guns to less accurate but that will affect your plane too (assuming you're in a fighter).
