I agree with Captain Stable and Muskat90. Rather pose OPEN questions than closed questions.
But as the Linate accident shows, sometimes one is vigilant (SAS) but the other guys are maybe not. It is all well to have situational awareness and not to fall prey to confirmation bias, only to have somebody do the wrong thing while you have the feeling that they are doing the right thing, but cannot actually see that they are doing the right thing, i.e. when in LOW VIS conditions.
We should all be more stricter with ourselves and always ask ourselves the "What if..." question.
A couple of good keywords:
Preparation
Teamwork
Vigilance
Trust
