Took a little over thirty minutes, and I was solo in a Longbow. After the first torp I dropped into her fighter bay and just started hammering away with guns. When she got down low enough, I flew out of the bay, turned around, shot off another torp and then got the hell out of there. Switched the camera to rear view and enjoyed the fireworks. Took 5300 shots from the guns and probably would have gone faster if I A) had put more power to the guns and B) had come armed with dumbfires.
