Star navigation
As an insomniac SLF and being mostly awake during night flights, I can tell looking at the sky at night if the plane is changing direction. I can even tell you which direction that would be, where are the planets if any are visible, trace the ecliptic and guess the approximate local time without looking at my watch. Ancient mariners had this skill practised a thousand times better than I. Do you mean to tell me that pilots would not know to navigate by the stars?
