I have no solution to the remote turret problem, but then again, I know little about writing code and therefore have know idea of how easily it could be done.
Luckily, I do have experiance... Let's just say that writing the game Snake (you know, get the pellets, make it grow, but don't run into yourself.

) in FLASH took me about 3 "days" (45 minute sittings) and about 250 (about 400 counting the highscore system I put in [internet high score, not just on own computer]) lines of code. I am unaware of what language AHII is programmed in, but from the looks of what I've seen, it's a version of C. And from what I've read on the issue, it'd be one helluvan obstical to have to jump around. The only bit of code that I've ever seen that was easy was in programming class, the teacher didn't want to teach that day, so our assignment was the make a console application that whenever started would say, "Hello world." in C#. Took us all 3 minutes to do, simply because it took the computer 2 mins and 45 secs to load the program we used to write the code.

Edit: Looking at my code I see ways to reduce the length down to about 50-75 lines of code (using an existing object as a key listener etc...)
If you get your uber fightERS then I should get my uber bombER.
See, the flaw in your argument is I'm a primary bomber. B-24 all the way.
I'm going to ask this question again and I would like a serious thought out answer.
How would adding the B29 as a perked bomber unbalance the game/arena?

You still haven't addressed the speed with altitude issue. As stated, it would run away from most anything we have forcing an attack from the rear (cannon).
