But if the pilot flies blind, has bad luck in correcting his drift, is dubious about his position, that peak begins to stir with a strange life and its threat fills the breadth of the night sky in the same way as a single mine, drifting at the will of the current, can render the whole of the ocean a danger.

— Antoine de Saint-Exupéry, Wind, Sand, and Stars, Ch. 1, The Craft, 1939, Harcourt Brace (1992 edition)
