flight

I have been digging around for my copy of Desert Solitaire because my memory is sure of an essay that perfectly describes the mixture of disbelief and awe that I feel every time I find myself sitting in air. 

But I didn't find it so this is what i wrote:

There is only hum and hiss and pressure in this loud silence that is thick and weighted with whispers.  I am full of absence -- but I would no sooner let go of all that I am missing than I would let go of my own soul.  I could not bear that lightness.
