The B-52 is proving quite a tricky one to get right. Some of the characteristics almost seem mutaully exclusive and it can be hard to reconcile them. For example, I found max speeds of 554 kts @ 21000 ft and 495 kts at 46500 ft but I can't get a working solution that'll climb that high. Another characteristic is the take-roll & clearence for a fifty ft obstacle these are 7000ft & 9100ft respectively, which is difficult to reconcile with the speed and alt ratings. Yet another 'unusual' characteristic are the flaps. These are pretty big but only have two positions - fully deployed (35deg) or fully retracted, with no in-between settings and can tend to produce huge pitch changes, which is the last thing you want in a relatively under-powered a/c like the B-52 at low speed. In other words, I dunno why it's not stalling properly.
