Add more gunners to the buffs.
In another life, we used to launch "Death Stars" with up to 10 on board. It was a riot.....given we are unlikely to fly huge box formations, a few more guns won't hurt. (We still got shot down by serious defenders).
You could grab a beer, sit back, and shoot the breeze with squaddies as you made your run on strategic targets.....
BTW, the gunner should get the same perks and points as the pilot, to make it worth making the ride........(likewise, the pilot should get fighter kill points earned by the gunner).
Hitech? What do ya think?
