Lost

On 20 December 1995, American Airlines Flight 965 is en route to Cali, Colombia. The crew members are asked if they would like to perform a straight-in approach to Cali. The pilots accept the offer, but as they are making the necessary changes, they inadvertently remove the waypoints from the flight plan in their flight management system (FMS), causing them to become unsure of their exact position. The crew members' mistakes leads them to fly the aircraft into a 9,000 foot mountain near Buga. Only four passengers and a dog survive.
