SAETA Flight 232
On 15 August 1976, SAETA Flight 232 en route from Quito, Ecuador, to Cuenca was reported missing while in flight. The SAETA-operated Vickers Viscount 785D carried 55 passengers and 4 crew members.
Searches of the possible crash area produced no results. A mid-route crash on the stratovolcano Chimborazo was considered to be most probable, though some speculated a guerrilla hijacking.
The plane was eventually found at 5,310m in October 2002 by two members of the Nuevos Horizontes mountaineering club, Pablo Chiquiza and Flavio Armas, while exploring a new route to the summit of Chimborazo via the Garcia Moreno Glacier. However, they did not report it immediately. The discovery wasn't confirmed until February 2003, when a team hired by the television station Teleamazonas went up to film a video of the wreckage, and found human remains, newspapers from the day the plane disappeared and identification cards of known passengers.
