Rather curious description this photographer gave to his photo which, eventually, I understood!
These poor souls are the last few survivors of a plane crash over a tiny unknown island. The vapour trails of the mid-air collision are even now still visible in the clear blue sky. Statis and unmoving, as if time itself had deserted them.
Isolated from civilisation the suvivors begin to invent strange rituals and take to wearing plain white robes found in a long abandoned underground bunker.
