It's easy to talk in the theoretical but when planes have crashed loosing all hands and in similar circumstances pausing and taking a look at the data is the best course of action. Planes are grounded precisely because there is no information. If we had information, then there wouldn't be a grounding (because we can rule out design flaws, etc). When you are driving in a snow whiteout do you not slow down or even pull over? Or are you one of those people who would drive at the regular high way speed limit while not knowing what's in front of you?
