1947 Avianca Douglas DC-4 crash Wikipedia
On February 15, 1947, an Avianca Douglas DC-4 registered C-114 crashed into Mount El Tablazo en route from Barranquilla to Bogotá, Colombia, killing all 53 people on board.
Mount El Tablazo was shrouded in fog when, at 12:18 local time, the aircraft crashed into it at an elevation of about 10,500 feet. The cause of the crash was determined to be pilot error, with the crew deviating from the designated airway and flying below a safe altitude.
The crash was the deadliest aviation disaster of 1947, and was eventually tied with the crash of an Eastern Air Lines DC-4 near Baltimore three months later.
