2 August 1947: At 1:46 p.m., G-AGWH, operating British South American Airways Flight CS59, departed Buenos Aires, Argentina enroute Santiago, Chile. At 5:41 p.m., Santiago airport received a routine Morse code signal indicating the flight would arrive in four minutes. It never arrived. Its fate remained a mystery until 1998, when two mountain climbers on Mount Tupungato, one of the highest mountains in South America, 50 miles east of Santiago, found a wrecked Rolls-Royce Merlin engine in the melting ice of a glacier at 15,000 ft.
