Gorgeous pics! An AC-130 will be an interesting addition to the gameplay.
It doesn't look like it's flyable - the gunner screen-cap shows only him in the plane. After I thought about it, I suppose it will help maintain the atmosphere of it all. A decent pilot would be bored flying a slow pattern, and there would be no end of hi-lar-ious hijinx ramming a tank with a gunship.
both of those slots are gunner slots. The slot itself has a different icon based on the player role. Makes sense considering the ac130 has multiple guns. But it does suck that you can't fly it.
But... I do recall in desert combat mod for BF1942 they added an ac130 and most of my time flying it was really spent slowly crawling the desert floor with it as a giant indestructible tank. Also you could just land in their base and grab the flag and nobody could stop you because you were an ac130. I'd wager that only 10% of pilots would fly it correctly, and only 10% of the time they'd be the one that gets the pilot seat. So no flying makes sense.
After looking at that screenshot that does make sense to have it be more a passenger role only. I wonder how often you are able to jump into one. What is the respawn rate? Do you respawn into an airborne one or does it take off and it AI controlled? I love the sound design of the series so I am curious how it will sound when rounds come flying into the area. COD made it sound pretty cool.
