On 26 August 1981 it was being operated by a Vickers Viscount turboprop airliner registered in Colombia as "HK-1320" when it collided with Mount Santa Elana, an Andean mountain peak, destroying the aircraft and killing all 50 on board.

Vickers VC10 build a prototype which they designated the "Type 1000" (Vickers V-1000), followed in June 1954 by a production order for six aircraft for the RAF. The planned civil airliner was known as the "VC7" (the seventh Vickers civil design). Development was prolonged by the need to meet the RAF's requirements for short take-off and a self-loading capability. Work started on the prototype but by 1955 the aircraft's increased weight required a more powerful engine, causing BOAC to question the engine development cycle. In 1955, the government cancelled the RAF order in a round of defence cuts. Vickers and the Ministry
