David Morris was on the Cornish coast when he saw an astonishing sight: a ship seemingly floating in the air above the water.
A meteorologist explained this is a superior mirage produced by a rare atmospheric condition called temperature inversion, where cold air blankets the sea below a layer of warm air. The denser cold air bends light, producing the mirage.
(Hap tip Dan Hadash of Optics Lighting for letting me know about this one.)
Check it out here at the BBC website. And here for a separate sighting.
