SAETA Flight 011 crashes into the Chimborazo volcano in Ecuador, killing all 59 people on board; the wreckage is not discovered until 2002.

SAETA Flight 011 was a scheduled passenger flight operated by SAETA Air Ecuador between Quito and Cuenca, using a Vickers Viscount 785D aircraft. On 15 August 1976, the flight was reported missing near the Chimborazo stratovolcano while carrying 55 passengers and four crew members. Searches for the plane would be carried out for 26 years, until the wreckage of the aircraft was officially located in February 2003.

Chimborazo is a stratovolcano situated in Ecuador in the Cordillera Occidental range of the Andes. Its last known eruption is believed to have occurred around AD 550. Although not the tallest mountain in the Andes or on Earth relative to sea level, its summit is the farthest point on Earth's surface from the Earth's center due to its location along the planet's equatorial bulge. Chimborazo's height from sea level is 6,263 m (20,548 ft), well below that of Mount Everest at 8,849 m.

The country's capital is Quito and its largest city is Guayaquil.
