Crash of Air China Flight 129

Eleven seconds after the call on the emergency frequency, the second officer reported to the Tower controller that they were on the circle approach. At 11:20:17 the captain took over control from the first officer and said he was going to turn base. He slowly began a widening turn, causing the first officer to urge him: "turn quickly, not too late." Meanwhile the flight was cleared to land . At 11:20:32 the captain disconnected the autopilot and banked the plane to the right. Twenty-two seconds later the first officer cautioned: "Pay attention to the altitude keeping," and the captain asked him to help him get a visual on the runway. Due to the limited visibility they were not able to see the runway. The first officer then advised the captain to initiate a go around, but the captain did not respond. At 11:21:15 the first officer said, "Pull up! Pull up!" Pitch attitude was increased to 11.4 degrees but thrust was not increased. Two seconds later the aircraft impacted a mountain, about 4.6 km from the runway.
