Like most aircraft of that era, the B-17 was only marginal on all engines...on three with a full load it would be a handful.
Memory says that when I took my ride, the guns were wooden mock-ups which would weigh a small fraction of the 'real thing'. and only one had an ammunition belt. There were a few 'bombs' in the bomb bay, but just a few - not a full load. Granted, that was ~20 years after you flew it and Nine-O-Nine had been repaired a couple times during that interval.
