I like setting up a full complement of B-17Gs (x16), and setting the difficulty to Ace level, and seeing how many of them I can take down before they take me out.
If I'm hit and damaged beyond flyability/combat able, and not killed at the stick, I try my best to land the plane, or bail out.

Some of the many planes are better suited to this than others. Part of the fun is getting to fly each one to find out which is the best overall. 8-)
