The term 'white out' is one that is becoming greatly misused and seems
to imply, in simple terms, snowing very heavily. Provided that snow is
lying, it's possible to experience a white out without any snow
falling at all. All it needs is lying snow and mist sufficiently dense
to provide omni directional lighting conditions such that no shadows
are visible and the shape and form of the ground underfoot cannot be
determined.

I once heard a pilot with the British Antarctic Survey describe their
technique for landing on the ice surface in white out conditions - basically
fly straight and at a very slow descent rate until contact is made with the
surface, no point looking out the window. Of course the 'landing strip' is
enormous and completely flat.
