so what s i m sorry, go ahead. what s happened in this airplane is he was all over the place. he was too high on that visual glide path, he was too low at some points, he was too fast, initially, and then he got slow. now, when the airplane got slow, the first thing that should have happened is the man in the right seat, the first officer or i think he was also a captain should have said captain, you re too slow. and if the captain didn t do something to change that condition, meaning applying power, then the first officer should have done it for him. that s called cockpit resource management, and he didn t do that. so the airplane got even slower. in fact, it got so slow that the stall warning horn went on, and then the stick shaker activated. the stick shaker is the airplane s yoke, shaking back and forth. and it s the last-ditch effort of the airplane, saying to the pilot, hey, you got me too slow and we re going to crash if you don t add power or get this ....
Experienced pilots come in so slow, dangerously slow at stall speed, and right up to san francisco international airport a an approach that requires quite a bit of attention as you come in here, alex. tom, let me ask you because i think a lot of people are under the impression that in situations like this especially with landings and take-offs, the airplane s on-board computer systems kick in at a certain point if you are in danger and that did not seem to be the case with this flight. do we know why there wasn t sort of an automatic response to the plane flying too low and too slow? they were not yeah. they were not on auto pilot. they were flying manually. it was up to them to watch their air speed. now the stick shaker kicked in. that s the yoke, literally the pilot s controls. it start the shaking violently when the plane was trying to tell the pilots you re going too slow, too slow and it starts shaking the stick to get your attention. by that time it was too late. they goos ....
It s throttles down to flight idle. literally just turning over. producing enough thrust for control of the aircraft. at any given point, you can push it. the thrusters are what people think of as the throttles. you can push them forward. firewall them all the way and the engines spool up quite quickly but it takes a couple of seconds to do it. that s one thing this plane didn t have. there were only a couple of hundred feet if that above the water. they were at stall speed and know from the stick shaker and they literally i mean, the engines at flight idle. to go from flight idle to total power would take a couple of second and that s what we didn t have. richard, you know, we have been playing this exclusive video you are seeing now and i want you to stand by because i want to talk about that with you as well as with another aviation expert. we re going to play the video for you in its entirety and hear from the man who shot it. ....
But it s too late. the plane is flying way too slow. deborah hersman admits he says significantly below the speed of 137 knots. we believe it s somewhere 90, 109, 110 so it s considerably slower than it should have been. the stick shaker, what is extraordinary about these pictures and the authorities will be certainly looking at them very closely, is that there were so many survivors because the way this aircraft went down the runway, one point lifting its, watching the nose lift up in to the air, almost vertically and then coming back down again, that anybody survived the impact and the subsequent fire from such a violent trauma is really remarkable. i think that although we talk about survivable accidents, don, ....
Information from the flight data recorder and the cockpit voice recorder. let s talk about some of the highlights. we know seven seconds before the crash there was a call for an increase in speed, which means that the pilot knew that the aircraft was not going fast enough to make a successful landing. six seconds before the impact, they had what you call a stick shaker, which means the aircraft was in danger of stalling. if the aircraft stalls, you don t get any lift and you re really going to have an enormous problem. 1 1/2 seconds before impact, the pilot calls to initiate, quote, a go around. what that means is they knew there was going to be trouble. they wanted to abort the landing, make the airplane go up, if you will, and then make another circle to the runway and then try to land the plane once again. the question was asked to the ntsb chairperson if this ....
