Not only were the fins unable to move, the position they were stuck in was a very unhelpful position.

  Yes, and could speculate that the main engine fired 'wrongly' because the control code didn't take into account that the fins were locked.

    Hm, if I was the guy designing the control loop on that thing (not gonna happen in real world, but bear with me), I would definitely take into account the fins position - the real position, not the one I want them to be in. Not that it would have helped anyway in this case.

      I suspect that the code takes the fin's starting position into account in each planning cycle but also assumes that the fin will move as directed in the future.

        No rotary encoders on those things?
