I think phrases like "hanging by a thread" and "cheapens out" probably have more to with anxiety or alternate agendas than facts. For me, my issues would be related to not knowing what's going on. A simple announcement like "we are undergoing a medical evacuation and will work to address the stoppage as soon as the evacuation is completed" could have gone a long way. And then "We have identified the cause for the stoppage and plan to resume service in x minutes (shortly, after the next update, whatever). "
