ECLIPSE PICTURE FROM PLANE SHOWS CURIOUS REFLECTIONS
The cover picture of this week’s Science News Letter is from a unique, unretouched photograph, one of a series made by the Hayden Planetarium-Grace Eclipse Expedition. It is one of the occasional astonishing freaks that occur in photography.
It was made looking nearly directly west over the left wing of a Pan American Grace Airways airplane over the coast of Peru at an elevation of 25,000 feet, a second or two before totality of the solar eclipse of June 8.
