00:16March 27, 1977 The Deadliest Accident in Aviation History
00:21At Los Rodeos Airport on Tenerife, thick fog blanketed the small island airport after a
00:28bomb scare diverted flights from Las Palmas.
00:31Two Boeing 747s, KLM Flight 4805 and Pan Am Flight 1736 ended up on the same runway.
00:40The KLM plane, refueled and ready, was instructed to taxi the full length of the runway and wait
00:47at the end.
00:48The Pan Am 747 was still backtracking slowly to exit.
00:53In dense fog reducing visibility to near zero, communications broke down.
00:59The KLM captain, under time pressure from duty limits, misunderstood the tower's instructions.
01:06He thought he had takeoff clearance.
01:08Without clear confirmation, the KLM 747 began its takeoff roll at high speed.
01:15The Pan Am crew saw the approaching lights too late and tried to veer off the runway.
01:20The KLM plane struck the Pan Am from the side at 150 knots.
01:26Both aircraft exploded in massive fireballs.
01:30All 248 on KLM died instantly.
01:34335 of 396 on Pan Am perished.
01:39Only 61 survived from the front of the Pan Am jet.
01:42The disaster highlighted CRM failures, ambiguous phraseology, and the dangers of non-standard
01:49procedures, leading to global changes in ATC protocols and pilot training.
02:07335 of the Pan Am.
02:08August 12, 1985, the worst single aircraft accident ever.
02:12Japan Airlines Flight 123, a Boeing 747 SR, took off from Tokyo Haneda for Osaka with 524 people.
02:23Just 12 minutes later, at 24,000 feet, a loud bang echoed.
02:29The aft pressure bulkhead ruptured explosively due to fatigue cracks from a faulty repair seven
02:35years earlier after a tail strike.
02:37Boeing technicians used incorrect riveting techniques, weakening the structure.
02:42The failure tore off the vertical stabilizer, shredded hydraulic lines, and disabled all flight controls.
02:49The plane lost all hydraulic power, elevators, rudder, ailerons, everything.
02:56For 32 agonizing minutes, the crew fought desperately using engine thrust alone,
03:02making fergoid oscillations and wild turns.
03:05They managed partial control but couldn't prevent the inevitable.
03:09The 747 crashed into Mount Ozutaka at high speed, disintegrating on impact.
03:15Only four female passengers survived from the rear section.
03:20The investigation exposed maintenance errors and inspection oversights.
03:25This tragedy revolutionized pressure bulkhead repairs, non-destructive testing, and safety
03:30protocols across the industry.
03:48On June 1, 2009, Air France Flight 447, an Airbus A330, departed Rio de Janeiro for Paris with 228 people
04:00on board.
04:01Cruising at 35,000 feet over the Atlantic, the plane entered a thunderstorm.
04:07Ice crystals blocked the pitot tubes, causing unreliable airspeed readings.
04:12The autopilot and autothrust disconnected suddenly.
04:16The pilots, facing confusing alarms and conflicting instruments, reacted incorrectly.
04:21The first officer pulled back on the cider stick, putting the aircraft into a deep stall.
04:27Instead of lowering the nose to recover, they held back pressure, keeping the plane stalled.
04:33For over four minutes, the Airbus fell from the sky at a high angle of attack.
04:38The crew never understood the stall situation due to the loss of reliable airspeed data and poor
04:45crew resource management.
04:46The plane slammed into the ocean intact, killing everyone instantly.
04:51Investigations revealed sensor issues, inadequate high-altitude stall training,
04:56and human error as key factors.
04:59This tragedy led to major changes in pilot training and pitot tube designs worldwide.
05:08This tragedy led to major changes in pilot training and pilot training and pilot training.
05:28May 25, 1979, the deadliest aviation accident in U.S. history.
05:34American Airlines Flight 191, a McDonnell Douglas DC-10, was taking off from Chicago O'Hare bound for
05:42Los Angeles with 271 people aboard.
05:46During rotation, the left engine, number one, separated from the wing due to a damaged pylon.
05:53The pylon had been improperly maintained months earlier when a forklift damaged it during engine changes.
05:59As the engine ripped free, it flipped over the wing, severing hydraulic lines and damaging leading edge slats.
06:07The slats retracted asymmetrically, causing massive lift loss on the left wing.
06:12The plane rolled sharply left, climbed briefly, then cartwheeled and crashed into a trailer park just 31 seconds after takeoff.
06:21All 271 on board and 2 on the ground perished in the fireball.
06:26The NTSB blamed improper maintenance procedures and designed flaws in the DC-10's engine mounting.
06:33This crash grounded all DC-10's temporarily and forever changed engine pylon inspection standards.
06:51The NTSB lags below to returned of water for doing sailor storm.
06:51The NTSB was affected by the island and was vivir during anioningife pandemic,
06:51although visitoroly breaks Waver tips back to work.
06:51The NTSB can really increase the inner suspension of the airGRAM based in theенная operation.
