Fata Morgana Mirage Turns Aircraft Carrier Into 'Huge Bear' Off Cornwall Coast

Mike Hancock of St Ives Boats said a distant aircraft carrier off Cornwall's north coast morphed into towering blocks, a bear-like shape and even a pi symbol as he sailed near Portreath and Pendeen.
The image drew online guesses that it showed a ship, crane or other object, but Hancock said the fast-changing form was a Fata Morgana — a rare superior mirage that can invert and stack distant images.
A Fata Morgana forms when freezing air is trapped beneath much warmer air, creating an atmospheric duct that bends light sharply; moving air layers then make the distorted image flicker in and out of focus.
Hancock said he had seen mirages before but never one like this off Cornwall, where the horizon briefly appeared tripled and bent — an effect linked historically to ghost-ship legends such as the Flying Dutchman.

As climate patterns shift, will the surreal Fata Morgana mirage become a more common danger for modern sailors?
