Well, if the visibility is such that the arriving aircraft can't see you and
it lands on top of you, then it's unlikely that sitting kind of sideways
would allow you to see him.

It is unwise to =depend= on somebody seeing you. It might not be the
visibility that prevents the arriving aircraft from noticing you, or
perhaps from doing anything about it (one might have taxiied into
position in error, detected later by the laws of physics)

except there's no God, and there's no dice. And maybe there's no universe.
