00:01A Boeing 767 is completely destroyed.
00:04People were on the ground, too weak to move.
00:08129 people are dead.
00:11I was surprised that anybody survived.
00:13It's the worst air disaster in South Korean history.
00:17What are they doing here?
00:19They should be all the way down there.
00:22Investigators face puzzling evidence.
00:25Help me find the runway.
00:27And why he didn't say, let's get out of here, let's miss the approach, we don't understand that.
00:32Start from the timing again.
00:35Could a few critical seconds aboard Air China Flight 129 have made the difference between life and death?
00:50It's crazy.
00:57Air China Flight 129 has been in the air for a little less than two hours.
01:10Among the 155 passengers is a group of Korean tourists flying home from vacation.
01:16Their tour guide is 28-year-old Seoul Iksu.
01:20I had just started a new job and my wife was four months pregnant.
01:25There were about 20 people traveling with our agency.
01:28There were about 20 people traveling with our agency.
01:32I had many things to take care of.

01:39Captain Wu Jinlu heads the Chinese flight crew.
01:49Captain Wu Jinlu heads the Chinese flight crew.
01:52He has more than 6,000 hours in the cockpit.
01:5418 degrees, dew point one six.
01:55First officer Gao Li-ji has over 1200 hours in the 767.
01:59Expect radar vectors to left downwind.
02:00The most junior member of the team is second officer Hu Jingying.

02:08Captain Wu Jinlu heads the Chinese flight crew.
02:10He has more than 6,000 hours in the cockpit.

02:15First officer Gao Li-ji has over 1200 hours in the 767.
02:18Expect radar vectors to left downwind.
02:20The most junior member of the team is second officer Hu Jingying.
02:24There was a third pilot in the cockpit.
02:27A second officer who was doing the radio calls.
02:30And that was because of his proficiency in English.
02:34They're piloting a Boeing 767-200.
02:38Built in 1985, it's 17 years old.
02:43Air China is the flagship carrier of the People's Republic.
02:47Its fleet of 68 planes flies routes across all of Asia and beyond.
02:52The airline has a stellar safety record with no serious accidents.
03:02Flight 129 is flying southeast from Beijing to Kim Hei International Airport in Pusan, South Korea.
03:10It should be on the ground in less than 30 minutes.
03:14Approach checklist.
03:21Tavern pressure set.
03:22Okay.
03:25Targeting speed.
03:27127.
03:31Altimeter setting.
03:33Set to 3000.
03:34The crew is ready to descend.
03:37They run through their approach checklist.
03:40Recall.
03:42Check complete.
03:44Approach checklist completed.
03:47I just can't believe that happened.
03:48I was working very hard because I had ambitions to be promoted.
04:02I didn't take breaks and work late.
04:05I was trying my best.
04:06But for Sol Iksu, who's trying to make a good impression in his new job, today is feeling like a disaster.
04:16I mean, what kind of person does that?
04:19It all started to go wrong this morning, when he made a mistake that he worries could get him fired.
04:25I had arranged for the group to sit in first class.
04:30But right before we got to the airport, I realized that I'd left my passport and bag in the hotel lobby.
04:37The bus driver had to turn around and go back to the hotel.
04:40The good seats were first come, first served.
04:41Because we had to return to the hotel, my group was pushed to seats at the very back of the plane.
05:01Some of the travelers were very angry.
05:06Don't touch my purse.
05:07I even told the group that I would return my tips.
05:18Sol Iksu has no way of knowing the far more important impact of this minor mistake.
05:24Ladies and gentlemen, we're about to begin our approach to Kim A airport.
05:28Local weather is foggy, with some rain.
05:31We'll be landing in approximately 20 minutes.
05:37Kim A tower, Air China 129. Good morning. With you now.
05:43Fifteen minutes before landing, the crew contacts the airport approach controller.
05:49Air China 129, Kim A approach. Fly heading 190, descend to 6000.
05:54Roger. Turn heading 190. He's sent to 6000.
06:00In this case, the co-pilot started the approach. He was actually the pilot flying.
06:04The captain was really monitoring his altitude, because the captain is a non-flying pilot.
06:10Captain Jin Lu has landed at Kim He three times before.
06:14It should be smooth sailing on approach.
06:16Air China 129, turn left heading 160.
06:24Descend to 2600.
06:26Turn left heading 160. Descend to 2600.
06:30Visibility is not very good.
06:34Kim He airport is near Korea's southern coast. An area known for unpredictable weather.
06:46Regarding the weather at the airport, I don't think there was anything unique about this particular day.
06:52There were clouds, there was rain.
06:55Gear down. Gear down.
06:58Last one.
07:06Runway in sight.
07:08Runway in sight.
07:12Air China 129, contact tower 118.1, circle west.
07:16Circling approach is a visual approach.
07:19The pilot has to maintain sight of the runway the entire time.
07:22If the weather is accurate, he should be able to conduct this approach and still keep his eye on the runway.
07:33The controller didn't get a response to his last radio call.
07:44The wind is too strong. It's very hard to fly.
07:46Changing weather conditions are posing a challenge for the crew.
07:54Clear to land runway 18.
07:59Reduce speed.
08:01Okay.
08:03Sol Ixu worries that the bad weather will delay their arrival in Busan.
08:07I thought the plane was circling because of foggy weather.
08:08I thought the plane was circling because of foggy weather.
08:14I thought the plane was circling because of foggy weather.
08:17I thought it was a strange thing.
08:19I thought it was a strange thing.
08:21The tower controller struggles to track the incoming 767 through thick clouds.
08:27Air China 129, are you able to land?
08:31Need to land.
08:41Let's go around.
08:45Rock, rock!
08:48I heard people screaming.
08:51I was sliding.
08:55I was sliding. I couldn't keep my body straight because the speed was too fast.
09:04Then, bang!
09:07All of a sudden, the plane stopped.
09:26I thought I was dead.
09:56I wasn't able to think about anything, not even my family.
10:13Light was coming through a gap.
10:23I realized it was coming from outside.
10:46Flight 129 crash survivor Sol Ixun
10:50Inches his way through a tangle of wires, crushed cabin debris, and razor-sharp aluminum fragments.
10:57Finally, he emerges into daylight, alive, but still not sure if he's out of danger.
11:12After the crash, I smelled fuel.
11:19I was certain it was airplane fuel.
11:21Air China flight 129 has crashed into the side of Mount Dotdei, miles from the intended runway.
11:38More than 3,000 emergency responders swarmed the site.
11:45The crash site was horrible.
11:51It was truly a miracle that they were able to find a number of survivors from such massive crash.
11:58Of the 166 people on board, 37 survive.
12:06Almost all those who made it out alive were seated near tour guide Sol Ixun.
12:1390% of the tour group I was traveling with survived.
12:19The fact that the young tour guide forgot his passport, something he thought was a shameful mistake, will be remembered forever as a life-saving stroke of luck.
12:29Korean air accident investigators arrive on the scene, along with American investigators from the National Transportation Safety Board.
12:47You could tell the whole area had been cleared out by the impact of the whole aircraft, and pieces were spread all over the place.
12:59I was surprised that anybody survived.
13:04Let me put those.
13:10From the crash site, investigators can see the airport nearly three miles away.
13:16There is no simple explanation for why Flight 129 hit terrain so far from the runway.
13:23What are they doing here? They should be all the way down there.
13:28It was obviously in a landing mode. What would cause him to get this low, this far out?
13:36He should have been well above this terrain.
13:39You wondered, why did this guy hit a hill?
13:42Keep me posted. The captain survived. Let's hope he can tell us something useful.
13:52Investigators learned that the only surviving member of the flight crew is Captain Wu Xinlu.
13:58It was surprising that the captain survived the crash because the impact forces are usually worse than the front of the airplane.
14:05If he does survive, and he's truthful, it can help an investigation a lot, because then you find out what really is going on.
14:15With the captain on his way to hospital, investigators focus on what the crash site can tell them about the accident.
14:22Debris is scattered for hundreds of yards down the hillside.
14:27It was over a large area. I was surprised it was so big.
14:32Normally, when an incident occurs, the wreckage and debris tend to stay within the area of their initial impact point.
14:44The widely scattered wreckage begins to paint a picture.
14:49Hey, take a look at this. The tail section landed over there. The front of the plane is all the way over there.
15:01The back of the plane must have landed first. Meaning the pilot was pulling up as the plane hit the ground.
15:08Flight 129 did not nosedive into the ground. Instead, the evidence suggests that at the last moment, the crew was trying to avoid hitting the mountain.
15:19If that's the case, it would help explain why some people survived.
15:24If he hadn't have done that, it may have been worse. But the airplane kind of cushioned itself a little bit into the trees.
15:31And impact forces were lessened as the airplane hit the ground, tore the engines off and slid through the trees so that people survived.
15:40But the central question remains unanswered.
15:43Why did Flight 129, in the midst of a seemingly routine landing, crash into a mountainside?
15:53The answers investigators need may lie with the plane's black boxes.
15:57Searchers have pulled the critical devices from the wreckage.
16:02But it will take expert lab analysis before anyone knows if the data can be recovered.
16:08I'm going to go down to the airport, talk to air traffic control, see if they've got anything to say.
16:15After any plane crash near a runway, some of the first people investigators want to speak to are the air traffic controllers.
16:23They were slated to perform a straight-in approach, but there was change to a circling approach.
16:29All of a sudden change.
16:31The wind changed direction.
16:33I changed the approach so they can land into the wind.
16:36Switching from straight-in to a circling approach is something that happens routinely at airports around the world.
16:42Some airports, you have to come one way in because of mountains or whatever, and then once you get to the airport, because of winds, you may circle and land.
16:53Flight 129 was originally scheduled to land on runway 36L, coming in from the south.
17:00But after the change, they were headed for runway 18R, coming in from the north instead.
17:09We're closer to sea. The weather is always changing. We do this all the time.
17:15Air traffic control gave them clearance for a circling approach, which was appropriate for the weather conditions at the time.
17:26Is there anything else you can remember?
17:37Communications. The radio communications were all wrong.
17:41How do you mean?
17:45Air channel 129, contact tower 118.1, circle west.
17:49Shortly after he instructs flight 129 to do a circling approach, the tower controller tells the pilots to switch to a new radio frequency.
18:02Air channel 129, contact tower 118.1.
18:09When the controller told the crew to switch to the tower frequency, they didn't acknowledge.
18:16Air channel 129, please contact 118.1.
18:22Air channel 129, please contact 118.1.
18:25The tower had to remind them, call them a couple of times.
18:31This is Kim Hei Tower on guard. Air China 129, if you hear me, please contact 118.1.
18:38The tower eventually called the cockpit on emergency frequency.
18:42Emergency frequency.
18:44All airports use a standard frequency to communicate in emergency situations.
18:49If air traffic control even suspects a plane is in distress, they will use this frequency to contact the crew.
18:56Kim Hei Tower, Air China 129, circular approach 188.
19:01Air China 129, check wheels down.
19:04Wind 210 at 17 knots.
19:07Clear to land runway 188.
19:12They finally called me back.
19:14It seemed like we're finally back on track.
19:15Then less than a minute later, they crash into the mountain.
19:22The Air China crew was slow to respond to air traffic control.
19:26Investigators need to know what was going on in the cockpit during the unusual delay.
19:31If air traffic controllers make a statement and the crew either doesn't answer or misinterprets it, it can cause the accident, basically.
19:46Oh, just a minute, please.
19:48Hello?
19:51Captain Wu Xinlu is the only member of the cockpit crew from Air China 129 to have survived.
20:12He may be the one person alive who knows what led to the fatal crash.
20:16It was hard to tell what injuries he had, but he was not in good shape.
20:22It wasn't life-threatening, I don't think, but it was not good.
20:25It was going to take him a while to recover.
20:30When I went to interview Captain Wu, he couldn't move, but he was clearly conscious to answer all the questions that the investigators asked.
20:41Was there anything mechanically wrong with the plane?
20:46No.
20:48Everything seemed fine.
20:54Then suddenly, the mountain seemed to come out of nowhere.
21:00Let's go around! Pull up! Pull up!
21:02Pull up!
21:03Pull up!
21:04Pull up!
21:08It was the typical sea fit, controlled flight into a terrain accident.
21:13That is to say, worse aircraft under pilot control is unintentionally flown into the ground.
21:21And the flight crew members are not aware of the impending disaster until too late.
21:27Did you have any difficulty communicating with the tower?
21:35No.
21:41Everything was normal.
21:44Controllers have already told investigators that the radio communication was far from normal.
21:50It's a troubling contradiction.
21:52Is there anything else you can tell us?
21:55Investigators wonder if the last-minute change to the approach presented any problems.
22:01Air China 129, this time active runway change 18R.
22:07Wind 210 at 17 knot.
22:11Expect circling approach.
22:15Circle approach runway 18R.
22:17Using runway 18R.
22:20Pilots should be alert for anything, and they should be thinking ahead.
22:25They should be thinking, well, I'm gonna land on this runway, but what happens if I have to do a circling approach?
22:32Did this cause you any difficulties?
22:37No.
22:39It was fine.
22:41This is what we're trained to do.
22:43Captain Wu stated that all he could remember was he saw a hill before the crash.
22:52And next he found himself bleeding around the accident aircraft.
22:59Nothing I heard in the interview in the hospital indicated that there was anything wrong.
23:07I mean, aside from, well, what happened.
23:12The crash near Busan is the worst air disaster ever on Korean soil.
23:19129 fatalities.
23:22As family members mourn the victims, pressure mounts on the investigation.
23:27How could a plane coming in for a routine landing suddenly hit a mountain?
23:32In this case, the crash was collected by the main parts of the aircraft.
23:35The crash was collected by the main parts of the aircraft.
23:37The crash was collected by the main parts of the aircraft.
23:39The crash was collected by the main parts of the aircraft.
23:41Lab technicians have managed to recover all the data from the Air China Flight Data Recorder.
23:48Things like the plane's speed, altitude, heading, and other critical flight parameters right up to the moment of impact.
23:55Investigators are eager to learn more about the circling approach.
24:02An approach the captain says posed no difficulties.
24:06Around here they should be circling in for a landing.
24:11But they just keep going.
24:14Then they crash into the mountain.
24:16Why didn't they turn here?
24:19They were a lot farther out than they realized.
24:25How are they supposed to do this approach?
24:28Pass me the training manual.
24:30Every airport has detailed procedures on how to approach its runways.
24:35Pilots are trained to follow these procedures to the letter.
24:37Gears down. Flaps 20. Turn 45 degrees. Parallel to end of runway start timer.
24:47Let's get this on the board.
24:50The landing procedure for Pusan calls for pilots to use a cockpit chronometer to aid with a circling approach.
24:57By timing maneuvers to the second, they should be more precise.
25:01But a cockpit timer can't guarantee a safe landing.
25:07If you set a timer and it's your procedure to do that,
25:11and you don't make sure that that procedure is followed,
25:16you're defeating your whole purpose of having a timer in the first place.
25:19So gear down here.
25:21Then they're supposed to do a 45 degree turn for 20 seconds here.
25:24Then they're supposed to make a 45 degree turn for 20 seconds here.
25:31You time it out 20 seconds, you turn parallel the runway,
25:35and then you make up what's called a base turn, 180 degree turn, and land on the runway.
25:41Here they should see the end of the runway.
25:4420 seconds later, they should have made their base turn.
25:48Despite what the captain has said, it looks like he got off to a bad start on the approach.
25:55The flight recorder showed that the pilot did not execute his first turn.
26:00He's supposed to make a left turn to begin the circling approach,
26:04and he's supposed to do that aggressively.
26:07He didn't turn steep enough with a steep enough bank.
26:12How fast were they going?
26:13They soon learned that bank angles weren't the only problem on the approach to Pusan.
26:19158 knots?
26:22That's much too fast.
26:25The aircraft was flying about 20 knots faster than it should have.
26:29Flying at too high a speed, they covered the downward leg more quickly than expected,
26:35which left them less time to prepare for the final turn.
26:38It's interesting that such a thing as 20 knots fast can make such a difference,
26:45but the truth is, it does make a difference.
26:49They're doing this all wrong.
26:52What were the pilots thinking?
26:55It's now clear that the crew of Air China 129
27:02mishandled the early stages of their approach to Pusan.
27:06But what's still a mystery is why the experienced pilots failed to correct the problem
27:11in time to make a safe landing.
27:16In 1992, an Air Inter flight bound for Strasbourg, France,
27:20met a tragic end similar to Air China 129.
27:24Flying in low cloud on final approach,
27:27the Airbus A320 plowed into a mountainside 12 miles from the runway.
27:3787 people died.
27:42The investigation revealed that the crew was unfamiliar with the plane's sophisticated computer interface.
27:48The pilots accidentally selected a dangerously fast descent speed.
27:553300 feet per minute.
28:00By the time they realized they were in danger, it was too late.
28:04Were the Air China pilots unfamiliar with some critical task?
28:13Something that might explain why they failed to execute a fairly routine approach?
28:18Korean investigators dig into their work histories in search of clues.
28:22Certified as a first officer in January 2002.
28:27Completed his first flight on the Boeing 767 in February.
28:32That's just two months ago.
28:34What about the captain?
28:40He had close to almost 6,300 hours on the 767.
28:43They learned that while the first officer was relatively new to the 767 cockpit,
28:49the captain was very familiar with the plane.
28:52But then, they uncover something remarkable.
28:56He's never done a circling approach at Kimi Airport before.
29:00Records show that not even in his simulator training had the captain attempted the approach.
29:06His training was only done in the simulator simulating a circling approach at Beijing Airport.
29:15That doesn't get you prepared for an airport like this with the high terrain around it.
29:21They had plenty of flight time, but I guess they never encountered this kind of a situation.
29:27To me, the fact that the crew had never done a circling approach is not good.
29:33Not good.
29:36Still, pilots have charts in the cockpit that explain landing procedures.
29:41Crews land at unfamiliar airports all the time.
29:45There must be more to the story.
29:48Is the cockpit voice recorder ready yet?
29:51So far, investigators have uncovered evidence of a crew flying too fast on approach
29:57and mishandling an initial turn.
29:59Now, they need to figure out why the rest of the approach went so catastrophically wrong.
30:08Everybody ready?
30:10Let's start from the very beginning of their approach.
30:13They hope the cockpit voice recording will provide some answers.
30:17Approach checklist.
30:19Having a pressure set.
30:21Okay.
30:23Targeting speed?
30:25One, two, seven.
30:27Everything seems to be in order so far.
30:29Let's keep listening.
30:31Air channel one, two, nine, can be approached.
30:34Fly heading one, nine, zero, descend to 6,000.
30:37Roger.
30:39Turn heading one, nine, zero, descend to 6,000.
30:41So now they're on approach, about nine minutes from scheduled landing.
30:57Up to now, they think they're coming in here.
31:01But the controller changes it to here.
31:04Remember, the pilots have never done this before at this airport.
31:09Air channel one, two, nine.
31:11This time, active runway change, one, eight, right.
31:14Wind two, one, zero, at one, seven, naught.
31:18Expect circling approach.
31:21Circle approach, runway one, eight, right.
31:25We're using runway one, eight, right.
31:27So they immediately acknowledge their circling approach.
31:31The flight is now just minutes from disaster.
31:36Investigators listen closely for anything that might explain the fatal flight path.
31:42Minimum descent altitude is 700 feet.
31:46600, 700, 700 feet.
31:51The pilots continue their checklist.
31:53We exit on this side taxiway.
31:57What's it called?
31:59Charlie 6.
32:01It soon becomes clear they've missed a critical step.
32:04After we land, we can move directly using taxiway Charlie 6.
32:11Stop.
32:14They're talking about what to do after they land.
32:17But they never did a proper briefing for the actual landing.
32:19Flight rules require commercial pilots to review every aspect of a landing beforehand.
32:24It's called the approach briefing.
32:26The approach briefing should have every eventuality that could take place during the approach.
32:32Now, switching from a straight in to a circling is unusual, but it should have still been discussed.
32:43They didn't fully review their landing procedure, let alone what they had to do to execute a final approach.
32:50Someone's supposed to call a checklist and say, approach briefing.
32:55And then someone's supposed to give approach briefing.
32:57When that didn't happen, somebody's supposed to speak up and say, hey, captain, or first doctor.
33:02We didn't do approach briefing. That's crew coordination.
33:04The missed briefing helps explain why the crew botched their initial turn.
33:11It also points to a level of carelessness in the cockpit.
33:15But what the CVR reveals next will leave investigators in total dismay.
33:20Okay, let's see what else they say.
33:29Runway inside. Runway inside.
33:32Investigators listen as the Air China crew, now just moments from a fatal impact, continue an approach that they never discussed in advance.
33:41Air China 129, contact tower 118.1, circle west.
33:50You see the end of the runway?
33:54And the runway is to the right.
33:56This is Kim Hei Tower on guard, Air China 129. If you hear me, contact 118.1.
34:04The crew is overwhelmed by the unfamiliar approach and fails to respond to the controller.
34:09Timing.
34:12Wait, where's my stopwatch?
34:15Investigators know that a circling approach demands precise timing of the turning maneuvers.
34:21Okay, start from the timing again.
34:24If you hear me, contact 118.1.
34:30Here's where they start the timer.
34:34Timing.
34:35The captain relies on his cockpit chronometer.
34:39In exactly 20 seconds, he must begin his final turn.
34:42They had to fly the aircraft away from the airport, and then turn on to final, and then land in the opposite direction.
34:52The wind is too strong. It's very hard to fly.
35:00I have control.
35:02Remarkably, Captain Wu Xinlu responds to his first officer's concern over wind speed by taking over the flying duties.
35:10He makes the switch at the worst possible moment.
35:14What is happening in that cockpit?
35:17One of the critical things in this particular accident was the switching of control during the 20 seconds.
35:24In the middle of the 20-second timer, he decides to take control. It's crazy.
35:31By suddenly taking control of the plane, the captain increases his workload at a critical moment and diverts his attention from the timer.
35:40Not only does he have to fly the airplane, he's got to manage the crew and other activities. He's got to monitor the radio calls.
35:50It confused the first officer. It made the division of duties uncertain. They didn't know what person was supposed to do what.
36:00When he takes control, the captain should clearly spell out the division of duties. Most critically, he needs to tell the first officer to keep track of the timer, but that never happens.
36:13Once he gets to the end of the timer, he says he's going to turn, but he doesn't.
36:19There was a lot of confusion listening to the CVR. A lot of confusion and lack of coordination in the cockpit.
36:27Turning right. The U-turn back to the runway should begin at the 20-second mark.
36:34But with the captain now flying and the first officer looking for the runway, no one starts the turn.
36:41The whole idea of timing on a circling approach is to get your certain spacing from the runway.
36:49And again, if there's winds, you have to adjust your timing and your angles of turns.
36:55Turning right.
36:57In this case, the breakdown in communications within the cockpit, they did not take account of the timing.
37:04And they just kind of maneuvered the airplane where they thought it should go.
37:08It was a total breakdown in approach procedures.
37:12And as investigators are about to discover, the confusion in the cockpit only gets worse.
37:17Do you have the runway in flight? No, I can't see out.
37:21Low cloud is now blocking the pilot's view of the runway.
37:26Turn! Turn now!
37:27A circling approach falls under visual flight rules. If pilots lose sight of the runway at any time, they are trained to immediately abort the landing and go around to try again.
37:41Passenger safety should have been the pilot's primary concern. And so, maintaining visual contact with the runway, the highest priority.
37:53I was truly surprised to find out that they proceeded with the landing approach without having the runway in sight.
38:06Turn! Turn now!
38:07It was getting pretty nasty. And why he didn't say, let's get out of here, let's miss the approach, that's, we don't, we don't understand that.
38:20Flying a 767 into a cloud on a visual circling, which all circling approaches are, is unacceptable.
38:34It's not professional.
38:39This shouldn't have happened.
38:40They've just lost sight of the runway, and they're here. Seconds from the mountain.
38:50Investigators have discovered that the pilots of Air China Flight 129 continued with their approach to Busan, even though they could no longer see the runway.
38:59The captain is supposed to go around when he can't see the airport. And he didn't do that. He continued turning and following instructions, trying to get back to the runway, which is totally wrong.
39:13Help me find the runway.
39:16They have also now dropped below the minimum safe altitude. But only the first officer seems to have noticed.
39:24Pay attention to your altitude.
39:25They were supposed to level off at a certain altitude. They went right through it.
39:31It's getting hard to fly at water altitude.
39:34The captain continues to descend for almost 30 seconds before his first officer finally speaks up.
39:41Must go around! Hold up! Hold up!
39:45But it's too late.
39:48No!
39:49No!
39:50Oh!
39:52No!
39:54No!
39:55Corrine, corrine.
39:58Corrine, corrine.
39:59Corrine, corrine.
40:14This is an anatomy of a botched approach.
40:19You never fly into a cloud on a circling approach.
40:23If you do, you should be initiating a go-around to get out of that situation.
40:31It's pretty basic stuff, it really is.
40:35It's something a Cessna 172 pilot should be able to do, as well as a 767 pilot.
40:46The captain is interviewed eight times over the next three months.
40:51Investigators never learn why he failed to initiate a missed approach after losing sight of the runway.
41:00The most basic of all visual flight rules.
41:04Who knows what the captain was thinking of?
41:10It's just hard to tell.
41:16Human can make mistakes.
41:21All of us are human beings.
41:23Though investigators can't know for sure, the captain might have been able to react to his mistakes sooner, if he'd been flying a newer version of the Boeing 767.
41:34His 17-year-old plane was not equipped with the latest technology, used to warn pilots if they're flying too low.
41:42This airplane had in it a ground proximity warning system.
41:47Unfortunately, this was an older model.
41:50And it did go off.
41:52It gave a warning, but it was way too late for the pilot to react.
41:56And this accident airplane, Air China, did not have the enhanced GPWS.
42:02It was recommended.
42:03They just hadn't done it.
42:05If it had been installed, it may have missed the mountain.
42:08After the accident, my life changed a lot.
42:19Instead of being happy about being alive, I had to live for the people who died in the crash.
42:25It has been very difficult.
42:38Three years later, on March the 4th, 2005, the Korean Aviation Accident Investigation Board finally publishes its accident report.
42:49The causes of this accident are basically human factors.
42:54It was poor crew coordination.
42:57It was poor communications, intracockpit and between the tower and the cockpit.
43:03It reinforced the need for proper training of flight crews.
43:08Key recommendations include providing better training for pilots on circling approaches,
43:14and a review of in-flight briefing procedures.
43:17In the aftermath of the Flight 129 disaster, Air China designates Kim Hei as a special airport.
43:28All pilots are now taught how the area's challenging terrain may affect takeoffs, landings and go-arounds.
43:36This should be used as a teaching point for aviators, why you give an approach briefing.
43:43And a thorough one, not just a standard one.
43:46And the hard part is, if you're flying day in and day out, to do this again and again and again.
43:53But it's necessary.
43:55It really is.
43:56You can see why.
43:58Come and see, cách to be done here.
