British newlyweds killed in helicopter crash on Greek island of Sifnos

On a sun-warmed afternoon above the Aegean, a private helicopter fell from the sky over Sifnos, carrying with it a British couple at the very beginning of their married life and the pilot entrusted to guide them safely. Three people died where joy had been intended — on an island chosen for its beauty, at a moment chosen for its promise. Preliminary signs point toward mechanical failure, and investigators now face the quiet, methodical work of understanding how a machine meant to carry people safely became the instrument of their end.
