Aloha Airlines Flight 243: The Day a Boeing 737 Lost Its Roof at 24,000 Feet
- Apr 27
- 13 min read
On April 28, 1988, a short inter-island hop from Hilo to Honolulu became one of the most dramatic survival stories in commercial aviation history. Twenty minutes into the flight, 18 feet of fuselage tore from the roof of a Boeing 737, exposing six rows of passengers to the open sky at cruising altitude. One flight attendant was swept to her death. Thirteen harrowing minutes later, the crippled jet landed safely on Maui, with one engine gone, an uncertain nose gear, and a cockpit hanging from buckled floor beams. Of the 95 people on board, 94 came home. And the aviation world was never the same again.
The Aircraft: A Record-Breaker in the Wrong Sense
The Boeing 737-297 at the centre of this story, registration N73711, had a name: Queen Liliuokalani, after Hawaii's last reigning monarch. Built in 1969 as the 152nd Boeing 737 ever produced, she'd spent her entire working life making short hops between the Hawaiian islands, Hilo to Honolulu, Maui to Kona, Honolulu to Lihue, racking up cycles at a rate Boeing had never anticipated.
By April 1988, the aircraft had accumulated 89,680 flight cycles and 35,496 flight hours. Those 89,680 cycles matter enormously. A flight cycle, one takeoff and landing, one inflation and deflation of the pressurised fuselage, is what drives metal fatigue in an aircraft skin. Boeing designed the 737-200 with a service life of 75,000 cycles. Queen Liliuokalani had already blown past that threshold by nearly 20,000 cycles, and at the time of the accident she was the second-highest-cycle Boeing 737 in the world. Her near-identical sister ship, N73712, held the top spot.
To put that in perspective: each of those flights averaged roughly 20 minutes in the air. The aircraft had essentially been inflated and deflated like a balloon, tens of thousands of times more than Boeing had ever stress-tested for in the real world. In laboratory conditions, a 737 fuselage section had been pressurised 150,000 times without failure, but those tests couldn't account for corrosion. In Hawaii's salty, humid coastal environment, corrosion was everywhere.
This wasn't entirely unknown to those responsible. In October 1987, just six months before the accident a Boeing inspection team visited Aloha Airlines and was alarmed enough to advise taking several 737s out of service for 30 to 60 days for "total structural overhaul." Aloha's management never acted on it. Boeing, citing customer confidentiality, blocked the FAA inspector from even attending the meeting where those findings were shared.
The Crew
In command was 44-year-old Captain Robert "Bob" Schornstheimer, who had logged 8,500 flight hours, of which 6,700 were on the 737. Beside him was 36-year-old First Officer Madeline "Mimi" Tompkins, with 8,000 hours total and 3,500 on the 737. An FAA air traffic controller was riding along on the cockpit jump seat, a routine arrangement for regulators familiarising themselves with airline operations.
The cabin was in the care of three flight attendants. Lead purser was Clarabelle "CB" Lansing, 58 years old and a 37-year veteran of Aloha Airlines who'd joined the airline straight out of high school in 1951 and had appeared in Aloha's advertising over the years. Passengers and colleagues alike adored her. "She was very personable," recalled Honolulu regular Dale Randles. "You could ask her anything and she'd answer your questions." Also working the cabin were Jane Sato-Tomita, a 14-year Aloha veteran, and Michelle Honda, who would later become the defining human story of the disaster.
The Flight: April 28, 1988
Flight 243 departed Hilo International Airport at 13:25 HST with 90 passengers and 5 crew. It was the seventh and final island hop of Queen Liliuokalani's day. The first six flights had been uneventful. This one showed no signs of being different. Weather was clear, the pre-departure walkaround turned up nothing unusual, and the cockpit crew seemed relaxed, pointing out landmarks as the 737 climbed toward its cruising altitude of 24,000 feet.
One passenger, later identified as Gayle Yamamoto, had noticed what looked like a crack near the forward door as she boarded. She said nothing. She didn't want to cause a fuss. Twenty minutes later she'd be staring at the open Pacific sky through the hole where the first class ceiling used to be.
The flight attendants were already serving drinks despite the fasten seatbelt sign still being on. This was standard practice on Aloha's ultra-short routes. CB Lansing was at row 5, handing a passenger a drink. Passenger William Flanigan, on an anniversary trip to Hawaii with his wife, watched her from the first class section. "She was just handing my wife a drink," he later told The Washington Post. "She had stopped and told us this was the last call. We were going to be descending. And then, whoosh! She was gone. Their hands just touched when it happened."
13:46: The Roof Tears Off
At 13:46, approximately 23 nautical miles south-southeast of Kahului, Maui, a section of the left fuselage wall gave way with a thunderous whoosh. In a fraction of a second, a crack that had been growing through hundreds of rivet holes for years raced across the lap joint, up and over the roof, down the opposite side. An entire 18-foot section of the upper fuselage skin, interior panels and all, simply departed the aircraft.
The violence was almost incomprehensible. The cockpit door blew straight off its hinges. The floor buckled upward near the first rows as pressurised air forced its way out of the hold below. Five crosswise floor beams snapped. The cockpit itself dropped more than a metre relative to the fuselage, hanging on by the tensile strength of the remaining floor structure alone. Captain Schornstheimer looked back to find "blue sky where the first-class ceiling had been."
Passengers in the first six rows were sitting in open air at 24,000 feet, held in place only by their seatbelts. The oxygen delivery system was destroyed, and those who reached for masks found nothing. Debris had been flung into the wings, engines, and tail. Wires flailed in the gale-force wind.
CB Lansing was gone. According to passengers seated nearby, she was blown upward and to the left in the initial decompression. Her body has never been found. The US Coast Guard cutter USCGC Cape Corwin led a three-day search involving helicopters, planes and vessels. All in vain.
There's a secondary hypothesis, proposed by pressure vessel engineer Matt Austin, and it's hard to dismiss once you've heard it. Austin suggested the fuselage may have initially opened a ten-inch square vent, just as the tear strips were designed to allow, but that Lansing's body became momentarily wedged in the opening rather than being thrown clear. That temporary blockage, he argued, would have caused a sudden pressure spike inside the escaping airstream, what engineers call a fluid hammer or water hammer effect, which then overloaded the surrounding weakened structure, causing the catastrophic failure. The NTSB acknowledges the theory is possible but considers the multiple-site fatigue cracking explanation more strongly supported by the evidence.
Michelle Honda: Crawling Into Aviation History
Flight attendant Michelle Honda had been near the tail section when the decompression hit, knocking her to the floor. The blast blew her shoes off. Her stockings shredded. Her clothing was soaked in other people's blood. She kept her eyes open in the narrowest slits she could manage against the flying debris. When she tried to shout commands, nothing came out.
She got up anyway. She crawled forward along the aisle, rung by rung, holding onto the metal bars under the seats. The closer she got to the hole in the fuselage, the more violent the wind became. "I didn't know if I would have stayed in the aircraft if I let go," she later said, "and I wasn't about to find out." Passengers reached out and grabbed her arms as she passed, steadying her. She told them to put on their life vests.
Near the worst of the damage, she found her colleague Jane Sato-Tomita unconscious on the floor, her head split open, lying under debris at the edge of the open section. Honda tried to drag her clear but couldn't move her alone. Instead she asked nearby passengers to hold Sato-Tomita down so she wouldn't be swept out. A ceiling panel had landed on passengers' heads, so Honda heaved it into the empty rear rows.
She tried the interphone to reach the cockpit. The cable had been severed. In a moment of desperate improvisation she still can't fully explain, she turned to a nearby male passenger and asked if he could fly a plane. "I think everybody had that look," she later said of the passengers around her. "Their eyes were searching."
She crawled back down the aisle. She spotted the island of Maui ahead. She lay down next to Sato-Tomita and held on. At 13:58, the aircraft touched down.
On the ground, Honda managed the evacuation alongside off-duty Aloha crew member Amy Jones-Brown. She later visited every injured passenger in hospital. Twice. When praised for her heroism afterward, she consistently rejected the label. "I was just doing my job." The NTSB praised the cabin crew's conduct as "exemplary."
In the Cockpit: Flying Blind
First Officer Tompkins had been flying when the decompression occurred. Captain Schornstheimer took over immediately and initiated an emergency descent: 290 knots, 4,000 feet per minute. The noise was so extreme that the pilots couldn't hear each other speak. Schornstheimer used hand signals.
Tompkins set the emergency transponder code 7700 and repeatedly called Honolulu Center. No reply came. She eventually reached Maui tower at 13:48, three minutes into the emergency, and declared she was inbound with a rapid depressurisation. The controller's repeated response of "say again" came back several times before she got the message across.
As they descended toward Kahului Airport, problems compounded. The left engine failed, not from debris ingestion but because the corroded throttle cable running through the buckled floor simply snapped. The nose gear wouldn't give a positive "locked down" indication, though the controller could visually confirm it appeared to be down. The plane was handling strangely due to damage to the flight control cables.
They couldn't raise full flaps either: at 15 degrees the plane shook alarmingly, so they came in at a higher speed with flaps at 5. On one engine. With an unconfirmed nose gear. With the cockpit still drooping from five broken floor beams.
Airport staff who saw the approach reportedly dropped to their knees. One photograph taken by a passenger in the moments after evacuation shows Tompkins standing in the doorway and Schornstheimer near row 1, surrounded by the carnage of what had been a first class cabin. At 13:58 and 42 seconds, exactly 13 minutes after the roof came off, the 737 touched down on Runway 02 at Kahului Airport.
Aftermath: Chaos on the Ground
Maui had no emergency plan for a mass-casualty aircraft incident. The island had only two ambulances. When the plane stopped and the evacuation slides deployed, 65 injured passengers poured onto the apron. The air traffic controller only called for one ambulance around the time of touchdown. When it arrived seven minutes later, the crew found dozens of people in urgent need of care.
The solution came from an unlikely source. Air traffic control radioed a local tour company, Akamai Tours, and asked for as many of their 15-passenger vans as could be spared to transport the injured to Maui Memorial Hospital, three miles from the airport. Two of the Akamai drivers turned out to be former paramedics. They set up triage on the runway. It was improvised, chaotic, and ultimately it worked.
In total, 65 people were injured, eight of them seriously. Among those most critically hurt was an 84-year-old woman who'd been struck by flying debris, sustaining multiple skull fractures. Jane Sato-Tomita, who'd been unconscious on the floor for the entirety of the descent, was evacuated with severe head lacerations and a concussion. The aircraft itself was dismantled on site. The damage was so extensive it couldn't be flown away.
The missing section of fuselage was never found. Neither was CB Lansing.
Why Did the Roof Come Off? The Investigation
The NTSB investigation found the aircraft wasn't just old. It was riddled with fatigue. When investigators examined a scrap of fuselage skin that had embedded itself in the leading edge of the right wing during the accident, they found at least five fatigue cracks that had been growing for more than 20,000 cycles and should have been visible with proper inspection techniques.
The root cause lay in how the early Boeing 737s were built. Queen Liliuokalani, the 152nd 737, was among the first 291 aircraft produced using a cold-bond epoxy process to join the overlapping aluminum skin panels at lap joints. The problem: the epoxy was temperature-sensitive and prone to delaminating. When bonds failed, water could infiltrate the joints, corroding the underlying metal. With the bonding gone, pressurisation loads transferred entirely to the rivets. The countersunk heads created a stress concentration called a "knife edge" that cracked under repeated cycling.
Boeing knew about this from 1972 onward and changed its production process for all 737s from frame 292 onwards. It also issued service bulletins to operators of early aircraft. But correcting existing aircraft required robust ongoing inspection, and Aloha Airlines was systematically failing to conduct.
The airline had never completed the required eddy current inspections (a technique using electrical currents to find cracks invisible to the naked eye), despite a 1987 FAA airworthiness directive requiring them. It had never replaced the countersunk rivets with protruding-head fasteners as mandated by a subsequent directive. Fuselage inspections were conducted at night under incandescent hangar lighting, often by inspectors with two hours or less of formal training. Most maintenance workers had no specialised training in non-destructive testing, and the airline employed not a single qualified engineer.
The NTSB later found that inspectors had patched at least 24 existing cracks on the aircraft, which meant some deterioration had been spotted, but missed hundreds more. The fuselage of Queen Liliuokalani, upon closer examination, was so riddled with linked fatigue cracks that two of her sister ships, N73712 and N73713, were immediately grounded and scrapped after inspection. A fourth, N73717, required a year of heavy repairs before it could safely fly again.
The NTSB's probable cause statement placed the failure squarely on Aloha's maintenance programme, with contributing failures from the airline's management, the FAA (which had approved extended maintenance intervals and never adequately followed up), and Boeing (which had failed to mandate a complete solution after knowing about the bonding problem for nearly two decades).
A Precedent: The 1981 Taiwan Crash
What makes the oversight even harder to accept is that a near-identical failure had already occurred, with catastrophic results. On August 22, 1981, a Boeing 737-200 operating Far Eastern Air Transport Flight 103 within Taiwan suffered a lap joint failure in its lower fuselage, broke apart mid-air over Sanyi township, and killed all 110 people on board. That aircraft had only 33,000 cycles, less than half of Queen Liliuokalani's tally at the time of the Aloha accident. The cause was identical: undetected corrosion and fatigue cracking at the lap joints.
The lessons from Taiwan in 1981 weren't applied in Hawaii in 1988. But after Aloha 243, no one in aviation could look away.
What Changed: The Legacy of Aloha 243
The regulatory and industry response to Aloha 243 was sweeping and lasting. The FAA issued emergency airworthiness directives within days of the accident, triggering inspections across the US 737 fleet that turned up 49 findings of cracks and corrosion in 18 operators' aircraft. In June 1988, the FAA held a formal Conference on Older Airplanes, launching a new policy of not just inspecting aging structures but mandating their replacement or modification.
Congress passed the Aviation Safety Research Act of 1988. The FAA launched the National Aging Aircraft Program, under which FAA inspectors directly observe maintenance work on aging fleets rather than reviewing paperwork after the fact. Boeing issued mandatory inspection directives for high-cycle 737s worldwide. The NTSB issued 21 recommendations spanning maintenance training, scheduling, inspection accountability, and corrosion control.
The critical conceptual shift was the recognition of Widespread Fatigue Damage (WFD), the phenomenon of dozens of small cracks developing simultaneously across a structure, collectively compromising its integrity even when no single crack appears catastrophic. In 2010, the FAA formalised this understanding into the WFD Rule (the Aging Airplane rule), requiring aircraft manufacturers to establish Limit of Validity (LOV) figures: maximum cycle counts beyond which an aircraft type may not fly without approved life-extension measures. The European Aviation Safety Agency (EASA) implemented equivalent rules.
The changes didn't reach every corner of the world in time to prevent all disasters. A China Airlines Boeing 747 broke apart in similar fashion in 2002 over Taiwan, killing all 225 on board. That, according to aviation analysts, appears to be the last fatal structural failure of a passenger jet attributable to unchecked metal fatigue. The revolution Aloha 243 triggered, however slowly it spread, reached its destination.
Remembering CB Lansing
Clarabelle Ho Lansing was born in 1930 and married Robert Earl Lansing, a US Marine Corps veteran from Redlands, California. They married in 1969. She joined Aloha Airlines as one of its very first flight attendants after graduating high school in 1951 and flew for the airline for 37 years without incident. She appeared in Aloha Airlines advertising and was considered the face of the airline's warmth and professionalism.
In 1995, a memorial garden was inaugurated in Terminal 1 of Honolulu International Airport in her honour (some sources give the formal opening as 1996) for the formal opening. She remains the only fatality of Aloha Airlines Flight 243. "She was a wonderful employee, a great lady," said Aloha spokesperson Stephanie Ackerman. "Our passengers loved her."
Her body was never recovered. Neither was the section of fuselage she was standing beneath when it tore away.
In Popular Culture
The accident inspired a 1990 CBS television film, Miracle Landing, in which the airline was fictionalised as "Paradise Airlines." The Mayday documentary series Mayday (Air Crash Investigation) has covered the incident in detail, and it's appeared in multiple books on aviation safety and disaster.
More than 37 years on, the photographs of that gutted 737, with rows of passengers in open-air seats, a thin aluminium floor the only thing between them and the Pacific, remain among the most arresting images in aviation history.
Captain Schornstheimer and First Officer Tompkins have described the experience in numerous interviews over the decades.
#Tompkins' voice can be heard on the air traffic control recordings, steady and precise even as the plane fell apart around her. Michelle Honda continued flying for some years after the accident, revisiting passengers in hospital and speaking publicly about the event and always refusing the word "hero."
The Most Damaged Airliner to Ever Land Safely
Aviation safety professionals generally regard Aloha 243 as the most severely damaged airliner ever to make a successful emergency landing. The aircraft touched down with no roof or walls in its first class section; five broken floor beams; failed wing and stabiliser leading edges; debris throughout the engines; a snapped engine throttle cable; a failed oxygen system; an uncertain nose gear; dozens of tripped circuit breakers; and electrical wires flailing in the open air.
