I know 295 00:21:25,558 --> 00:21:29,370 Pearson is almost at the runway, but he is much too high above it 296 00:21:29,394 --> 00:21:33,456 If he comes down at a normal descend rate, he'll miss the landing-strip 297 00:21:33,480 --> 00:21:38,480 but if he comes down steeply, his plane will gather a dangerous amount of speed 298 00:21:38,504 --> 00:21:42,386 he won't be able to stop before the end of the runway 299 00:21:42,410 --> 00:21:47,103 With a normal approach we have leading edge and trailing edge flaps 300 00:21:47,128 --> 00:21:49,722 which allow us to slow the air-plane down 301 00:21:49,746 --> 00:21:52,277 and fly at a slower speed, safely. 302 00:21:52,301 --> 00:21:57,019 We did not have real flaps as they run off the main hydraulic system 303 00:21:57,043 -->

00:22:10,612 and lose the excess of altitude 307 00:22:10,637 --> 00:22:14,332 On the other hand, I thought, it would take about 3 minutes 308 00:22:14,356 --> 00:22:20,183 and we were already descending at a rate of 2500 ft/min 309 00:22:20,207 --> 00:22:22,564 Only about 3000 ft above the ground, 310 00:22:22,589 --> 00:22:25,621 the plane doesn't have enough altitude to make a full circle 311 00:22:25,645 --> 00:22:29,027 It would hit the ground before making it back to the landing strip 312 00:22:29,051 --> 00:22:31,785 Pearson chooses a 2nd option 313 00:22:33,082 --> 00:22:35,082 Well, I guess I 'll just slip it 314 00:22:38,582 --> 00:22:41,816 Pearson decides to try a manoeuvre, called a side slip 315 00:22:41,840 --> 00:22:46,800 practically unheard of on commercial airliners, but sometimes used by glider-pilots 316 00:22:46,824 --> 00:22:50,668 and Bob Pearson has a lot of experience flying gliders 317 00:22:50,692 --> 00:22:54,621 I am just going to slip it down till we are almost at the end of the runway 318 00:22:56,848 --> 00:23:00,449 Side slipping involves what is known as crossing the controls 319 00:23:01,707 --> 00:23:05,535 Pearson plans to force the aircraft into a sideways free-fall 320 00:23:05,559 --> 00:23:09,988 allowing it to drop quickly without increasing its forward airspeed 321 00:23:10,215 --> 00:23:13,824 Pearson has never actually performed a side slip in a commercial aircraft 322 00:23:13,848 --> 00:23:17,746 but he is attempting one now in a Boeing 767 323 00:23:18,535 --> 00:23:27,123 The only way that I could control our speed was to induce drag in the fuselage 324 00:23:27,147 --> 00:23:31,225 by cross controlling the rudder and the elevators on the tail 325 00:23:31,249 --> 00:23:33,249 and the ailerons and the wingtips 326 00:23:33,273 --> 00:23:37,991 and causing the aircraft into a configuration 327 00:23:38,015 --> 00:23:42,991 Then, I can vary that to increase or decrease our speed 328 00:23:43,015 --> 00:23:45,585 or increase or decrease our descend rate 329 00:23:46,124 --> 00:23:50,028 Pearson controls the plane's descend by using his rudders and ailerons 330 00:23:50,053 --> 00:23:51,921 to chance the angle of the plane 331 00:23:52,358 --> 00:23:55,873 Crossing the controls involves tipping the wings in one direction 332 00:23:55,897 --> 00:23:58,686 but turning the aircraft in the opposite direction 333 00:23:58,710 --> 00:24:01,483 putting it side ways into the oncoming air 334 00:24:02,812 --> 00:24:06,280 As Flight 143 begins to drop towards the earth 335 00:24:06,304 --> 00:24:10,124 Quintal is about to discover something he did not expect 336 00:24:10,148 --> 00:24:14,179 The runway he trained at 15 years ago 337 00:24:18,352 --> 00:24:20,703 is no longer a runway 338 00:24:24,164 --> 00:24:26,930 Captain Bob Pearson is out of fuel 339 00:24:26,954 --> 00:24:30,006 out of engines, out of options 340 00:24:30,030 --> 00:24:34,912 If he can't line up with the runway at Gimli, he doesn't get a second chance 341 00:24:40,642 --> 00:24:42,900 Pearson turns the yoke left 342 00:24:42,924 --> 00:24:45,486 and pushes the rudders to the right 343 00:24:45,510 --> 00:24:47,510 The plane slips... 344 00:24:48,229 --> 00:24:50,229 ...to its left 345 00:24:53,088 --> 00:24:56,713 We were sitting in the CENTER, which is the heart of the air-plane 346 00:24:56,737 --> 00:24:58,447 so it is pretty solid there 347 00:24:58,471 --> 00:25:03,385 I thought there is a real good chance here that we'll be Al right 348 00:25:04,190 --> 00:25:10,033 However, when he put the air-plane into a side-slip all that went out the window was 349 00:25:10,057 --> 00:25:14,853 If he hits the wing or something, he starts to catapult and roll 350 00:25:14,877 --> 00:25:16,611 that is not going to work anymore 351 00:25:16,635 --> 00:25:21,533 The 767 loses altitude quickly, ploughing sideways through the air 352 00:25:21,572 --> 00:25:25,135 When I looked to the left of the aircraft, 353 00:25:25,159 --> 00:25:27,963 I was looking directly on the ground 354 00:25:28,869 --> 00:25:35,415 because the air-plane is angled quite, maybe 60° of bank 355 00:25:35,439 --> 00:25:40,962 The bank angle was quite high and the nose of the aircraft was quite high 356 00:25:40,986 --> 00:25:44,220 It was an awkward moment 357 00:25:44,244 --> 00:25:46,167 If it was awkward for me, 358 00:25:46,192 --> 00:25:51,143 I can imagine for the passengers, it must really have felt odd 359 00:25:51,167 --> 00:25:54,215 I saw a sand-trap from this golf-course 360 00:25:54,239 --> 00:25:58,184 And I thought: We are going to crash! 361 00:25:58,208 --> 00:26:01,168 Pearson must maintain a crucial balance: 362 00:26:01,192 --> 00:26:04,520 He has got to slow the plane enough to be able to land safely 363 00:26:04,544 --> 00:26:08,449 But if he slows down too much, the airliner could lose his lift... 364 00:26:08,473 --> 00:26:09,926 ...and plummet to the ground 365 00:26:09,950 --> 00:26:14,988 When a pilot is normally landing an air-plane he is manoeuvring the flight controls 366 00:26:15,020 --> 00:26:18,198 and operating the thrust levers... 367 00:26:18,223 --> 00:26:20,934 ...pretty continuously at most landings. 368 00:26:20,958 --> 00:26:25,082 So, I was doing the same thing (without the thrust levers) 369 00:26:28,659 --> 00:26:35,401 This is where I thought at my daughter Victoria, being alone with my husband 370 00:26:36,513 --> 00:26:40,276 and how he was going to cope with our daughter 371 00:26:40,300 --> 00:26:43,651 and how she was going to cope without having a mom 372 00:26:45,389 --> 00:26:48,553 As they approach, Pearson focuses on his target: 373 00:26:48,577 --> 00:26:50,818 The threshold of the runway. 374 00:26:50,842 --> 00:26:54,527 I got tunnel-vision like I have never had it before 375 00:26:54,551 --> 00:27:00,215 It was just our speed and our relationship with the threshold of the runway 376 00:27:00,239 --> 00:27:03,520 But now, only hundreds of feet from the ground, 377 00:27:03,545 --> 00:27:06,903 Quintal sees that their troubles are far from over 378 00:27:09,380 --> 00:27:12,130 The Gimli landing strip has been converted... 379 00:27:16,247 --> 00:27:18,247 ...into a drag racing strip. 380 00:27:21,872 --> 00:27:25,371 Today is Saturday and it is not just a race-day. 381 00:27:25,980 --> 00:27:28,691 It is a family day on the Gimli strip 382 00:27:29,902 --> 00:27:32,409 Racing is done for the day, 383 00:27:32,433 --> 00:27:36,776 but the airfield is filled with members of the local sport-scar-club, 384 00:27:38,245 --> 00:27:41,401 camping out with their families for the weekend. 385 00:27:46,511 --> 00:27:50,800 Two children have decided to peddle the length of the runway. 386 00:27:50,824 --> 00:27:53,378 They don't hear the plane coming for them 387 00:27:53,402 --> 00:27:56,183 without engines, it is silent 388 00:27:56,207 --> 00:27:59,972 And one thing the 767 doesn't have... 389 00:27:59,996 --> 00:28:01,527 ...is a horn. 390 00:28:01,551 --> 00:28:03,551 Brace, brace for landing 391 00:28:14,177 --> 00:28:16,762 The nose hit with quite a bang on the runway 392 00:28:16,786 --> 00:28:18,942 It was like a shotgun going off within feet 393 00:28:18,966 --> 00:28:21,755 The front landing-gear gives out immediately 394 00:28:21,779 --> 00:28:25,098 Pearson brakes hard, 2 tyres blow out. 395 00:28:26,567 --> 00:28:29,112 The bottom of the right engine scrapes the runway. 396 00:28:29,137 --> 00:28:31,137 I was a robot, no emotion at all 397 00:28:32,505 --> 00:28:35,504 Finally, Pearson sees what is in their path 398 00:28:35,528 --> 00:28:38,912 I looked up and could see two boys on bicycles. 399 00:28:38,936 --> 00:28:44,708 They must have been probably a 1000 ft down the runway for my position when I saw them 400 00:28:44,732 --> 00:28:48,209 At one point, I could see he raise his head 401 00:28:48,233 --> 00:28:52,122 And his surprise there is this big aircraft 402 00:28:52,146 --> 00:28:55,778 I can still remember the look of terror on their faces 403 00:28:55,802 --> 00:28:58,685 So, they were close enough for me to see that. 404 00:29:00,599 --> 00:29:02,575 With no nose-gear to steer with, 405 00:29:02,600 --> 00:29:05,443 Pearson's only hope of driving the plane left or right 406 00:29:05,468 --> 00:29:09,593 is by varying the brake pressure on the two main landing gear 407 00:29:09,617 --> 00:29:13,921 That is where my heart started to pitter patter a little bit 408 00:29:13,945 --> 00:29:19,382 The kids panic and try to outrun a plane that is travelling about 200 mph 409 00:29:19,406 --> 00:29:22,156 I knew I couldn't take the air-plane into these boys 410 00:29:22,181 --> 00:29:26,249 and I was going to take it off into the grass in the race-side 411 00:29:26,429 --> 00:29:30,507 There were campers along the West-side of the runway 412 00:29:30,531 --> 00:29:34,116 that I didn't notice until after we've touched down 413 00:29:34,382 --> 00:29:36,046 The nose was on the ground 414 00:29:36,071 --> 00:29:41,391 and I can still remember at the left side people standing by their barbecues. 415 00:29:41,415 --> 00:29:46,040 Dino Calvert is at the track with his friends for a weekend of racing. 416 00:29:46,219 --> 00:29:50,015 One of the gentlemen in the pits suddenly jumped in his car, he took off 417 00:29:51,032 --> 00:29:54,954 you don't drive like that in a pits usually 418 00:29:54,978 --> 00:29:58,883 I looked up and all I could see was smoke rising 419 00:29:58,907 --> 00:30:02,211 Pearson does all he can to stop the plane in time 420 00:30:02,235 --> 00:30:04,235 Holy crow 421 00:30:10,157 --> 00:30:14,633 The plane ploughs into a guard rail, installed on the middle of the runway 422 00:30:24,098 --> 00:30:26,809 17 minutes after running out of fuel, 423 00:30:26,834 --> 00:30:30,920 Air Canada Flight 143 comes to a final stop on the ground. 424 00:30:33,716 --> 00:30:38,169 Somebody yelled: Yahoo! or something and then people started applauding 425 00:30:38,193 --> 00:30:40,958 We were so grateful, we made it! 426 00:30:40,982 --> 00:30:44,430 When you believe you are going to crash, 427 00:30:44,462 --> 00:30:48,247 you do believe that the air-plane is going to break apart 428 00:30:48,271 --> 00:30:50,927 You are going to have fire 429 00:30:50,951 --> 00:30:52,951 EVACUATE! 430 00:30:54,998 --> 00:30:57,567 Thick smoke is quickly filling the cabin 431 00:30:57,591 --> 00:30:59,591 The crew doesn't take any chances: 432 00:30:59,615 --> 00:31:02,722 They want everyone off the plane as quickly as possible 433 00:31:02,746 --> 00:31:08,340 There was a sense of joy and then a panic 434 00:31:08,365 --> 00:31:11,206 We've got to get out of here 435 00:31:11,519 --> 00:31:13,327 Less than 2 months earlier, 436 00:31:13,352 --> 00:31:17,972 an Air Canada DC-9 made a successful emergency landing in Cincinnati 437 00:31:17,996 --> 00:31:22,878 only to burst into flames on the tarmac before all the passengers could get off: 438 00:31:22,902 --> 00:31:25,394 23 people died. 439 00:31:25,419 --> 00:31:29,889 The crew and passengers of this flight want to avoid a similar faith 440 00:31:30,726 --> 00:31:35,749 It took maybe just a few seconds to come to a full hold on the runway, 441 00:31:35,773 --> 00:31:39,124 but the cockpit was full of smoke 442 00:31:39,148 --> 00:31:41,148 Passenger evacuation checklist 443 00:31:43,366 --> 00:31:45,655 Fuel shut off 444 00:31:45,679 --> 00:31:47,679 Cabin pressurized 445 00:31:48,000 --> 00:31:50,000 Electrics off 446 00:31:50,024 --> 00:31:51,188 Checklist complete 447 00:31:51,212 --> 00:31:53,212 Time to get out of here 448 00:31:57,852 --> 00:31:59,852 Come on guys, get a fire extinguisher 449 00:31:59,876 --> 00:32:02,633 We grabbed a fire extinguisher on our way 450 00:32:02,657 --> 00:32:07,211 You never go to a fire at a racetrack without having a fire extinguisher with you 451 00:32:07,235 --> 00:32:09,992 And we run up towards it 452 00:32:10,016 --> 00:32:15,156 the doors open up and you see the chutes come of, like a spider has growing legs 453 00:32:15,180 --> 00:32:21,062 The plane ended up eventually standing almost what appeared to be almost on its nose 454 00:32:21,461 --> 00:32:26,343 When I opened my door, and I saw that the chute was so steep 455 00:32:26,367 --> 00:32:31,382 I thought: Oh, my goodness, how do I get these passengers to go down? 456 00:32:31,406 --> 00:32:37,351 Due to the nose-down angle of the plane, the 2 rear slides don't reach the ground 457 00:32:39,914 --> 00:32:43,124 10 people are slightly injured during the evacuation 458 00:32:43,148 --> 00:32:46,031 most of them coming down the steep rear slides. 459 00:32:46,055 --> 00:32:52,680 I heard on the West radar frequency, one of the 767s says: 460 00:32:53,360 --> 00:32:56,750 He is down OKAY, He is in one piece 461 00:33:02,070 --> 00:33:04,834 I said: OKAY! 462 00:33:04,859 --> 00:33:09,859 because all of these people were going to sleep in their own bed that night 463 00:33:16,983 --> 00:33:20,968 There is still a lot of smoke, coming from the plane's nose 464 00:33:23,155 --> 00:33:27,967 It turned out it was about 6 inches of insulation between the inner and outer skin... 465 00:33:27,991 --> 00:33:31,389 ...from friction, that was starting to burn 466 00:33:31,413 --> 00:33:33,413 The flight attendances have good news: 467 00:33:33,437 --> 00:33:36,358 all 61 passengers have made it off the plane 468 00:33:36,382 --> 00:33:39,491 There is not so much as a single serious injury 469 00:33:48,227 --> 00:33:51,617 Bob Pearson has done what no one has done before: 470 00:33:51,641 --> 00:33:58,445 he safely landed a 767 with no engines, gliding to safety from more than 26,000 ft 471 00:34:09,327 --> 00:34:12,500 The event made international headlines immediately 472 00:34:12,524 --> 00:34:17,188 People are already asking how one of the most sophisticated passenger-planes in the world 473 00:34:17,213 --> 00:34:19,563 could have run out of fuel 474 00:34:25,387 --> 00:34:29,160 By the next day, the investigations has already begun. 475 00:34:29,332 --> 00:34:33,642 Bill Taylor and Diane Rocheleau of Canada's Aviation Safety Bureau 476 00:34:33,667 --> 00:34:36,636 are among the first investigators at the scene 477 00:34:36,660 --> 00:34:41,784 I was a junior mechanical engineer at the time I've been working for transport Canada for a year 478 00:34:41,808 --> 00:34:44,722 Going to the field for the first time was very exciting 479 00:34:44,746 --> 00:34:48,339 It was new, it was a major aircraft 480 00:34:48,699 --> 00:34:52,222 Once we got into the fuel-quantity indicating system 481 00:34:52,246 --> 00:34:59,753 I left Diane to deal with the specifics of the computer system 482 00:34:59,777 --> 00:35:04,167 First, Bill Taylor needs to confirm what everyone has been telling him: 483 00:35:04,191 --> 00:35:06,191 that the plane is out of fuel 484 00:35:07,214 --> 00:35:12,691 Investigators drain the tanks, collecting less than 17 gallons of fuel 485 00:35:12,715 --> 00:35:16,971 The 767 can hold almost 24,000 gallons 486 00:35:17,690 --> 00:35:22,058 It is like having 5 tablespoons of fuel in a midsize car 487 00:35:22,839 --> 00:35:27,652 Taylor next needs to examine the possibility that the fuel leaked out during the flight 488 00:35:27,676 --> 00:35:32,683 The other checks involved looking for any evidence of fuel having been lost 489 00:35:33,081 --> 00:35:38,229 I even went so far as to go into what they call the dry bay of the aircraft 490 00:35:39,081 --> 00:35:41,221 I'm a bit claustrophobic, so 491 00:35:41,246 --> 00:35:44,940 I really wasn't too enthusiastic about going up in there, 492 00:35:44,965 --> 00:35:48,527 but I crawled up and had a look around with the flashlight 493 00:35:48,552 --> 00:35:54,005 and confirmed that there was no evidence of fuel having been lost in there 494 00:35:54,029 --> 00:35:56,503 That leaves Taylor with only one conclusion: 495 00:35:56,527 --> 00:35:59,747 Flight 143 took off without enough fuel 496 00:35:59,771 --> 00:36:03,099 Now, investigators need to find out why 497 00:36:04,490 --> 00:36:07,997 Diane Rocheleau begins looking for the answer to that question 498 00:36:08,022 --> 00:36:12,740 in the plane's sophisticated electronics bay, located beneath the cabin 499 00:36:12,764 --> 00:36:16,107 The 767 was a newer type aircraft, 500 00:36:16,131 --> 00:36:21,334 It did have a lot of computerized systems and I guess back in 1982 501 00:36:21,358 --> 00:36:27,928 These were coming on to the market at a fast rate and they were newer types of electronic system 502 00:36:30,319 --> 00:36:35,381 Rocheleau confirms that a computerized unit, the digital fuel gauge processor, 503 00:36:35,405 --> 00:36:38,022 had been malfunctioning on this plane. 504 00:36:38,046 --> 00:36:41,803 There was no spare in Montreal, so it couldn't be replaced. 505 00:36:43,054 --> 00:36:46,007 Rocheleau takes the component for testing 506 00:36:46,032 --> 00:36:49,254 It was decided early on that the processing unit 507 00:36:49,279 --> 00:36:54,085 will be taken to the manufacturer, Honeywell in Indianapolis, for testing. 508 00:36:54,109 --> 00:37:00,265 And I was tasked with taking the unit, so we went through all the testing procedure 509 00:37:00,289 --> 00:37:04,789 At one point we did discover that it was a malfunction with the unit 510 00:37:04,813 --> 00:37:10,016 During the testing, we went more and more in depth and we found out that one of the circuits 511 00:37:10,040 --> 00:37:13,828 It is called an inductor coil, it was a very small part 512 00:37:13,852 --> 00:37:19,050 It was encapsulated at the manufacturer Encapsulated means it is covered with plastic 513 00:37:19,075 --> 00:37:20,606 You cannot visually see it, 514 00:37:20,631 --> 00:37:25,169 because it is covered with plastic and you cannot see the coil itself 515 00:37:25,193 --> 00:37:28,194 Once we took over the plastic case 516 00:37:28,219 --> 00:37:31,641 we could see that the solder joint had not been made properly 517 00:37:31,665 --> 00:37:34,461 which caused the malfunction in the system 518 00:37:36,680 --> 00:37:41,711 The faulty processor explains why Pearson didn't have fuel gauges for the flight 519 00:37:41,735 --> 00:37:45,109 but doesn't explain why he didn't have enough fuel 520 00:37:45,133 --> 00:37:48,953 The inoperative gauges were clearly flagged 521 00:37:48,977 --> 00:37:53,602 Ground crews wouldn't have relied on them when they were fuelling the plane 522 00:37:53,626 --> 00:37:58,002 Investigators confirm that the ground-crew did perform a manual check of the fuel 523 00:37:58,027 --> 00:37:59,415 before take off 524 00:38:01,993 --> 00:38:03,993 I just need to know what you did next 525 00:38:04,625 --> 00:38:07,113 We did a manual check of both tanks 526 00:38:08,550 --> 00:38:11,315 then, we pump enough fuel for the trip 527 00:38:11,682 --> 00:38:15,767 Flight 143 should have taken off with enough fuel for the trip 528 00:38:15,791 --> 00:38:17,791 Okay, thanks... 529 00:38:19,603 --> 00:38:21,603 ...it helps 530 00:38:29,027 --> 00:38:34,316 Investigators now have to figure out how one of the world's most advanced jetliners 531 00:38:34,691 --> 00:38:38,300 took off with half the fuel, necessary for its flight 532 00:38:41,253 --> 00:38:44,893 The investigators know, that with its fuel gauges out of service 533 00:38:44,917 --> 00:38:48,471 Flight 143's fuel tanks were checked manually 534 00:38:48,495 --> 00:38:52,588 Then, the fuel for the trip to Edmonton was added to the tanks 535 00:38:57,642 --> 00:39:00,290 But before the plane could be given more fuel, 536 00:39:00,315 --> 00:39:02,962 a crucial calculation had to be carried out 537 00:39:06,314 --> 00:39:10,579 Pilots need to know the weight of the fuel on their plane 538 00:39:11,376 --> 00:39:14,704 but fuel trucks pump jet-fuel by volume 539 00:39:19,556 --> 00:39:22,399 In order for pilots and fuellers to communicate 540 00:39:22,423 --> 00:39:27,430 a simple routine translation between volume and weight has to be made 541 00:39:41,054 --> 00:39:45,054 Investigators check and double-check that math. 542 00:39:51,763 --> 00:39:58,020 The fuelling records from the day of the accident provide the answers they have been looking for 543 00:40:02,543 --> 00:40:04,744 This is a typical fuelling record 544 00:40:04,768 --> 00:40:09,363 But when investigators examine the calculations for Flight 143 545 00:40:14,043 --> 00:40:16,918 ...they look anything but straightforward 546 00:40:16,942 --> 00:40:21,598 The document clearly shows the amount of fuel in the right and left tanks 547 00:40:21,622 --> 00:40:25,598 but investigators are troubled by two particular numbers 548 00:40:25,622 --> 00:40:28,465 One converts volume to kilograms 549 00:40:28,489 --> 00:40:30,489 the other converts it to pounds 550 00:40:30,513 --> 00:40:32,513 They shouldn't be using both 551 00:40:37,086 --> 00:40:40,453 So, did you convert to pounds, or to kilograms? 552 00:40:40,477 --> 00:40:42,477 To pound... 553 00:40:43,469 --> 00:40:45,469 ...no, to kilo 554 00:40:49,203 --> 00:40:51,500 Can I see that again? 555 00:40:51,524 --> 00:40:57,477 Further interviews with the technicians and crew reveal that the events on Flight 143 556 00:40:59,243 --> 00:41:03,149 were caused by human error, involving poor calculations 557 00:41:03,180 --> 00:41:05,508 and ultimately inadequate training 558 00:41:08,703 --> 00:41:13,373 The technicians, refuelling Flight 143, got muddled in their calculations 559 00:41:13,398 --> 00:41:16,203 while converting the volume coming out of the fuel truck 560 00:41:16,227 --> 00:41:18,788 to the weight of the fuel in the tanks 561 00:41:20,671 --> 00:41:24,965 No one who saw the calculations that day noticed the basic error 562 00:41:29,059 --> 00:41:30,502 In 1983, 563 00:41:30,527 --> 00:41:34,808 Canadian ground crews were used to converting the amount of fuel leaving their trucks, 564 00:41:34,833 --> 00:41:36,566 into pounds 565 00:41:38,723 --> 00:41:44,551 The 767 was the first plane in Air Canada's fleet to have metric fuel gauges 566 00:41:48,168 --> 00:41:50,753 Its fuel should have been measured not in pounds, 567 00:41:50,777 --> 00:41:54,082 but in kg s, which requires a different calculation 568 00:41:56,684 --> 00:42:02,973 Flight 143 needed 22,300 kg for the trip 569 00:42:02,997 --> 00:42:09,450 But pilots and technicians let it leave with 22,300 lbs instead 570 00:42:10,380 --> 00:42:15,630 Because a pound is about half a kilogram, the plane only got half the fuel it required 571 00:42:15,654 --> 00:42:19,872 which explains why Pearson's flight computer told him he had plenty of fuel 572 00:42:19,896 --> 00:42:23,380 He entered the wrong amount of fuel to start with 573 00:42:23,404 --> 00:42:27,232 In the past, the flight engineer calculated the fuel loads 574 00:42:27,256 --> 00:42:30,029 This accident raises an important question: 575 00:42:30,053 --> 00:42:33,342 Who's job was it with the two men crew? 576 00:42:33,373 --> 00:42:39,326 Better training is definitively an issue in an incident just as that 577 00:42:39,350 --> 00:42:41,908 If everyone is trained 578 00:42:41,933 --> 00:42:48,209 and the lines are drawn as to who is responsible for what 579 00:42:48,233 --> 00:42:52,978 then, there is no ambiguity on it, 580 00:42:53,002 --> 00:42:55,845 People know what they are responsible for 581 00:42:55,869 --> 00:42:59,822 In this case, it was open ended 582 00:42:59,846 --> 00:43:05,588 they were not aware who was responsible. 583 00:43:07,776 --> 00:43:11,244 A subsequent enquiry found that none of those involved that day 584 00:43:11,269 --> 00:43:13,745 was trained in metric calculations 585 00:43:13,769 --> 00:43:15,550 Not the ground-technicians... 586 00:43:15,575 --> 00:43:17,575 ...not the pilots 587 00:43:18,880 --> 00:43:21,411 I had not received any... 588 00:43:21,435 --> 00:43:26,880 neither of us had received any training at all, and do these calculations 589 00:43:27,669 --> 00:43:31,809 The computer that had replaced the 767's flight engineer was broken 590 00:43:31,833 --> 00:43:34,419 and no one knew who should be doing its job 591 00:43:34,443 --> 00:43:38,013 Air Canada 143 was essentially down a man 592 00:43:38,037 --> 00:43:41,989 The goal is to prevent a recurrence, this particular event 593 00:43:42,013 --> 00:43:46,823 We also find out other system that might have been either at fault 594 00:43:46,848 --> 00:43:50,063 or maybe they could cause a problem in the future 595 00:43:50,088 --> 00:43:53,074 and you do try to prevent a recurrence 596 00:43:57,825 --> 00:44:03,653 It took a string of mechanical and human failures for Flight 143 to run out of fuel 597 00:44:03,880 --> 00:44:07,520 but another failure that day may have saved some lives 598 00:44:09,622 --> 00:44:12,192 If the plane's nose-gear had not collapsed, 599 00:44:12,216 --> 00:44:15,356 it would have taken Pearson much longer to stop 600 00:44:15,466 --> 00:44:19,294 The plane could have slid into the people who were at the strip that day. 601 00:44:19,318 --> 00:44:22,262 which would have had catastrophic results 602 00:44:22,286 --> 00:44:25,887 There could have been more injuries or even loss of life 603 00:44:28,442 --> 00:44:32,731 Pearson and Quintal were partly blamed for their roles in the incident. 604 00:44:32,755 --> 00:44:36,764 A government enquiry recommended that Air Canada re-evaluate the training 605 00:44:36,789 --> 00:44:41,359 of flight-crews and ground-technicians in metric fuel conversions. 606 00:44:41,632 --> 00:44:45,257 It also recommended that the airline keep more spare parts, 607 00:44:45,281 --> 00:44:47,655 such as fuel gauge processors. 608 00:44:49,663 --> 00:44:56,709 Rick Dion retired in 2003 after a long career as Air Canada's coordinator of maintenance control 609 00:44:57,537 --> 00:45:02,763 First Officer Maurice Quintal was promoted to Captain, in 1989 610 00:45:02,787 --> 00:45:06,763 Captain Bob Pearson went on to fly 10 more years for Air Canada 611 00:45:06,787 --> 00:45:10,935 his experience at Gimli shaping the rest of his career as a commercial pilot 612 00:45:10,959 --> 00:45:17,029 This experience affected me mostly by making me more relaxed as a pilot, 613 00:45:17,053 --> 00:45:22,537 giving me the feeling that as much as I trained for all those years that: 614 00:45:22,561 --> 00:45:27,763 There is always that question about how you are going to perform when the chips are down 615 00:45:27,788 --> 00:45:31,840 And now, I have the feeling that no matter what as long as the aircraft stay together, 616 00:45:31,865 --> 00:45:33,958 we will get it safely back on the ground 617 00:45:34,443 --> 00:45:37,161 It is a relaxing experience 618 00:45:37,995 --> 00:45:42,693 It is the knowledge that you know: under stress, you can perform 619 00:45:43,293 --> 00:45:45,293 before that, you don't know 620 00:45:45,317 --> 00:45:48,887 You just hope you will and you train for it... 621 00:45:48,911 --> 00:45:50,512 ...but you never know 622 00:45:50,536 --> 00:45:54,879 With the things that they had to deal with was magnificent 623 00:45:54,903 --> 00:45:59,028 I think that it got proven in the simulator of Vancouver 624 00:45:59,052 --> 00:46:04,223 They tried out the same circumstances with several crews... 625 00:46:04,247 --> 00:46:06,247 ...and they all crashed 626 00:46:06,692 --> 00:46:11,146 Probably, the most important thing that came out of it is the realization that 627 00:46:11,170 --> 00:46:14,442 when something new is introduced 628 00:46:14,466 --> 00:46:19,622 special attention and training needs to be accomplished 629 00:46:19,646 --> 00:46:22,411 for people, to be aware, what they are dealing with 630 00:46:22,435 --> 00:46:26,106 When we had landed and the air-plane was all in one piece 631 00:46:26,130 --> 00:46:30,497 I thought: Wow, I got another chance and to fly again 632 00:46:30,521 --> 00:46:31,849 Because of a tragic like that, 633 00:46:31,874 --> 00:46:34,529 you want to take your deck of cards and fire it in the air 634 00:46:34,553 --> 00:46:36,169 You are truly free 635 00:46:36,193 --> 00:46:40,802 I guess from that point of view I find it very difficult to say, but 636 00:46:40,827 --> 00:46:44,013 Gimli was maybe almost the best thing that ever happened to me, 637 00:46:44,037 --> 00:46:47,108 next to meeting my wonderful wife and marrying her 638 00:46:48,217 --> 00:46:50,412 Two days after the landing at Gimli... 639 00:46:50,436 --> 00:46:56,435 ...Air Canada's 767 was back in the air on its way to Winnipeg for repairs 640 00:46:57,185 --> 00:47:01,435 A quarter century later, that same plane is still in service 641 00:47:01,459 --> 00:47:05,115 and it still carries the nickname that Bob Pearson earned it: 642 00:47:05,139 --> 00:47:07,139 The Gimli Glider 643 00:47:07,163 --> 00:47:11,311 Subtitles Rein Croonen 56662
