Thirteen people died after a flight carrying European tourists to see Peru’s Nazca Lines crashed outside the city of Nazca on Saturday. The Peruvian government said that the plane’s crew had reported a mechanical failure before it lost radio contact, according to CNN. The agency said in an official report that the plane’s pilot, Américo Salazar, and co-pilot, Irenka Guanilo del Carpio, were also killed. Peru’s Indigenous inhabitants etched the geoglyphs into the desert hundreds of years ago to create the famed Nazca Lines. The lines, which form images of animals, can only be fully observed from the sky or viewing towers.
