On December 20, 1995, American Airlines Flight 965, a Boeing 757-223, was on a scheduled passenger flight from Miami, Florida, U.S.A., to Cali, Colombia. Close to its final destination the pilots erroneously cleared the approach waypoints from their navigation computer. When the controller asked the pilots to check back in over Tulua, north of Cali, it was no longer programmed into the computer. They were lost and the aircraft crashed into a mountain. Of the 163 people on board, 4 passengers survived miraculously the accident.
