Thats right, I'm talking about the C-130 with the howitzer, 40mm and vulcan cannons on it. Seems to me that it would be hard to attack targets with at least some degree of percision when you have to aim all those guns by banking the aircraft while flying at reletivly fast speeds. Is there some technique that I dont know about or is targeting perhaps done by some integrated autopilot/targeting system which is programed to cirlcle and fire at a specific cordinate on the ground?

Here is an image of how the side firing guns work, with the aircraft flying in a circle and the guns firing down. If the aircraft orbits a particular position all that is needed to focus the fire is to change the "pylon".
Actually, the gun system is incredibly accurate. During Vietnam, the AC-130s had the ASD-5, a device that could find the electromagnetic emissions emitted by the ignition coils on Soviet trucks. They then cruised the Ho Chi Minh trail and knocked out truck after truck after truck with the 40mm guns. According to this site
