I originally thought I completed the game, but after reading about the complexity of the last mission, I'm pretty sure I didn't. I was never *that* good at flight sims.
I flew around in a F-16 a bit in free flight mode, under the Golden Gate, and out to the aircraft hangar.
I wanted to demonstrate the cool FS-UAE emulator to my brother, and launched Interceptor. Quickly remembering the controls, I ended up flying my F-18 under the Golden Gate bridge and landing it on the carrier on the first try!
Just wasting time with FS-UAE, I took off from the aircraft hanger with my F-18, and landed it perfectly again. I think this game plays best with all-keyboard controls.
