A 3-D scan of the reconstruction will be made for historical record. "[1]:294[53], Though the FQIS itself was designed to prevent danger by minimizing voltages and currents, the innermost tube of Flight 800's FQIS compensator showed damage similar to that of the compensator tube identified as the ignition source for the surge tank fire that destroyed a 747 near Madrid in 1976. [1]:289 This might well be the signature of an arc on cockpit wiring adjacent to the FQIS wiring. It takes a great deal of time and high-tech detective work to piece together the often seemingly disparate events in flight which, together lead up to a major accident., Oakley says the length of the Flight 800 investigation was due to a couple factors. [1]:6574 The green zone with the aft portion of the aircraft was located the furthest along the flight path. The aircraft had completed 16,869 flights with 93,303 hours of operation and was powered by four Pratt & Whitney JT9D-7AH turbofan engines. The FBI conducted an investigation into the crash to determine if terrorist action was involved in the tragedy; no such action was found in our investigation. [1]:256, At the start of FBI's investigation, because of the possibility that international terrorists might have been involved, assistance was requested from the Central Intelligence Agency (CIA). Flight 800 has begun releasing details to family members who request them. [34]:1[35]:34 This hotel became known as the "Heartbreak Hotel" for its role in handling families of victims of several airliner crashes. A full four years after the crash of TWA Flight 800, the NTSB released its official report: It found the probable cause of the accident was a spark in the center fuel tank that eventually led. [32]:2, With lines of authority unclear, differences in agendas and culture between the FBI and NTSB resulted in discord. The lighthouse statue was designed by Harry Edward Seaman, whose cousin died in the crash, and dedicated by George Pataki. Flight 800 is a seminal moment in aviation safety history, the safety boards managing director said in a 2021 statement. The spacecraft was exposed to re-entry temperatures of 3,000 degrees while traveling at 12,500 mph, or 18 times the speed of sound. Officials called off the search as Coast Guard crews were attempting to retrieve what they believed was a significant piece of wreckage, based on sonar detection and a bubbling pool of jet fuel at the ocean's surface. [24][25], The NTSB was notified about 8:50pm the day of the accident; a full "go team" was assembled in Washington, DC, and arrived on scene early the next morning. So far, Wetli said he cannot rule out a bomb as the cause, but he said he has found no evidence of one, such as metal and bomb parts trapped in bodies. The design and certification concept that fuel tank explosions could be prevented solely by precluding all ignition sources. [44]:12[52], The NTSB's review of the released witness documents determined that they contained 736 witness accounts, of which 258 were characterized as "streak of light" witnesses ("an object moving in the sky variously described [as] a point of light, fireworks, a flare, a shooting star, or something similar. [1]:290 The NTSB concluded that the most likely source of sufficient voltage to cause ignition was a short from damaged wiring, or within electrical components of the FQIS. [33] Many waited until the remains of their family members had been recovered, identified, and released. [1]:273274 Since none of the recovered CWT wreckage exhibited these damage characteristics, and none of the areas of missing wreckage was large enough to encompass all the expected damage, the investigation concluded that this scenario was "very unlikely". January 3, 1997. TWA's senior management had spent Wednesday celebrating in London. All but one were considered very unlikely to have been the source of ignition. Flight 800 has begun releasing details to family members who request them. [65], During the investigation, the NTSB and the FBI clashed with each other. ")[1]:230 The NTSB witness group concluded that the streak of light reported by witnesses might have been the actual airplane during some stage of its flight before the fireball developed, noting that most of the 258 streak-of-light accounts were generally consistent with the calculated flightpath of the accident airplane after the CWT explosion. [62], On July 18, 2008, the U.S secretary of transportation visited the facility and announced a final rule designed to prevent accidents caused by fuel-tank explosions. They reported their sighting to the tower at Suffolk County Airport. Various civilian, military, and police vessels reached the crash site and searched for survivors within minutes of the initial water impact, but found none,[1]:86 making TWA 800 the second-deadliest aircraft accident in United States history at that time. On July 7, 2021, 25 years following the crash, the NTSB will decommission the wreckage, which will be destroyed by the end of 2022. While some victims' bodies were mostly intact, most were either burned, fragmented, skeletonized, or decaying, so they had to be identified by DNA testing and dental records. John Purvis, head of the accident investigation unit for the Boeing Company at the time of the event, says airplane explosions are quite rare, in part due to security measures and equipment improvement. FACT CHECK: We strive for accuracy and fairness. So far, most of the recovered bodies that pathologists are examining have been "relatively intact," said Wetli, but he emphasized that "relative" is itself a relative term. Bodies and debris have been carried far from the crash site by tides -- requiring searchers to cover more than 400 square miles of ocean -- and large sections of the 747 jetliner have sunk more than 100 feet, likely with many of the missing bodies inside. Following its final report on the crash, the National Transportation Safety Board issued several safety recommendations including regular maintenance programs and design standards for fuel tanks. But even though we're physicians, we're still human. [30][31]:1 The search and recovery effort identified three main areas of wreckage underwater;[1]:65 the yellow zone, red zone, and green zone contained wreckage from front, center, and rear sections of the airplane, respectively. 22c, p. 68, Recovery locations of the wreckage from the ocean (the red, yellow, and green zones) clearly indicated: (1) the red area pieces (from the forward portion of the wing center section and a ring of fuselage directly in front) were the earliest pieces to separate from the airplane; (2) the forward fuselage section departed simultaneously with or shortly after the red area pieces, landing relatively intact in the yellow zone; (3) the green area pieces (wings and the aft portion of the fuselage) remained intact for a period after the separation of the forward fuselage, and impacted the water in the green zone. In this case, the victim was a Long Island dentist who had assisted forensic dentists in the medical examiner's office. [1]:118, Further examination of the airplane structure, seats, and other interior components found no damage typically associated with a high-energy explosion of a bomb or missile warhead ("severe pitting, cratering, petalling, or hot-gas washing"). To honor this agreement made with the families of the victims of TWA Flight 800, the NTSB will work closely with a federal government contractor to dismantle the reconstruction and destroy the wreckage. [1]:259, Although it was unable to determine the exact source of the trace amounts of explosive residue found on the wreckage, the lack of any other corroborating evidence associated with a high-energy explosion led the NTSB to conclude, "the in-flight breakup of TWA flight 800 was not initiated by a bomb or missile strike. [6], The four-year NTSB investigation concluded with the approval of the Aircraft Accident Report on August 23, 2000, ending the most extensive, complex and costly air disaster investigation in U.S. history at that time.

[1]:298, Computer modeling[1]:122123 and scale-model testing[1]:123 were used to predict and demonstrate how an explosion would progress in a 747 CWT. [54]:6. SMITHTOWN, N.Y. Autopsies reveal that most passengers aboard the ill-fated TWA Flight 800 died almost immediately in the air, sparing them the long plunge into the ocean after the plane broke. So the appearance of a missile was basically an optical illusion.. [1]:89, The NTSB addressed allegations that the Islip radar data showed groups of military surface targets converging in a suspicious manner in an area around the accident, and that a 30-knot radar track, never identified and 3 nautical miles (5.6km; 3.5mi) from the crash site, was involved in foul play, as evidenced by its failure to divert from its course and assist with the search and rescue operations. Despite the safety boards official findings, over the last two decades, conspiracy theorists, bolstered by eyewitness accounts reporting a missile strike, continue to charge that a terrorist attack, bombing or even friendly fire took down Flight 800. New York's Pataki asks feds to help pay for TWA recovery - December 27, 1996. EAST MORICHES, N.Y. (AP) _ The coroner said today he doubts that TWA Flight 800 passengers experienced the horror of a free fall and thinks most suffered an almost instantaneous death. Among the dead were 18 crew members and 212 passengers, including 16 students and five chaperones from Pennsylvania's Montoursville Area High School French Club. "[1]:259, To evaluate the sequence of structural breakup of the airplane, the NTSB formed the Sequencing Group,[1]:100 which examined individual pieces of the recovered structure, two-dimensional reconstructions or layouts of sections of the airplane, and various-sized three-dimensional reconstructions of portions of the airplane. Oakley notes that from the distant perspective of witnesses on the ground, the sequence of the explosion, a sudden shift of gravity and continuing forward momentum that caused a sharp temporary climb, and the planes vertical dive and fiery descent, the crash could have looked like the result of some sort of attack. The suspension prolonged an already arduous search. [1]:45[note 1][12][13][note 2], The ground-maintenance crew locked out the thrust reverser for engine #3 (treated as a minimum equipment list item) because of technical problems with the thrust reverser sensors during the landing of TWA 881 at JFK, prior to Flight 800's departure. He acknowledged that families of the victims are extremely impatient for their loved ones to be identified; 16 have been tentatively identified and the dentist colleague has been positively identified along with his wife traveling with him on Flight 800. The captain's CVR channel showed two "dropouts" of background power harmonics in the second before the recording ended (with the separation of the nose). Air travel safety, in general, has steadily improved since the beginning of the widespread use of jet aircraft in 1958, he says. [44]:7 From November 1996 through April 1997, this group reviewed summaries of witness accounts on loan from the FBI (with personal information redacted), and conducted interviews with crewmembers from a New York Air National Guard HH-60 helicopter and C-130 airplane, as well as a U.S. Navy P-3 airplane that was flying in the vicinity of TWA 800 at the time of the accident. The board determined that the probable cause of the TWA 800 accident was:[1]:308. These plugs were blown out following the explosion of Flight 800. As of 2005[update], NTSB and FBI personnel conduct joint exercises. The captain commented on the "crazy" readings of the number 4 engine fuel flow gauge about 21/2 minutes before the CVR recording ended. [1]:243247 Advocates of a missile-attack scenario asserted that some of these witnesses observed a missile;[1]:264 analysis demonstrated that the observations were not consistent with a missile attack on TWA800, but instead were consistent with these witnesses having observed part of the in-flight fire and breakup sequence after the CWT explosion. [1]:85, Because no evidence was found that an explosive device detonated in this (or any other) area of the airplane, this overpressure event could only have been caused by a fuel-air explosion in the CWT. The report on passenger Susan Hill, a homicide. From that investigation we issued safety recommendations that fundamentally changed the way aircraft are designed.. When investigative priority remains with the NTSB, the FBI must coordinate its investigative activities with the NTSB investigator-in-charge. [47][48] In addition, the backs of several damaged passenger seats were observed to have an unknown red/brown-shaded substance on them. As a subscriber, you have 10 gift articles to give each month. [51]:2 CIA analysts, relying on sound-propagation analysis, concluded that the witnesses could not be describing a missile approaching an intact aircraft, but were seeing a trail of burning fuel coming from the aircraft after the initial explosion. Notable passengers included:[20], In addition, 16 students and five adult chaperones from the French Club of the Montoursville Area High School in Pennsylvania were on board. Among other things, the act gives NTSB, instead of the particular airline involved, responsibility for coordinating services to the families of victims of fatal aircraft accidents in the United States. Investigators believe the explosion began in the center fuel tank, but they say. [1]:313 Meanwhile, initial witness descriptions led many to believe the cause of the crash was a bomb or surface-to-air missile attack. [1]:256257, Close examination of the wreckage revealed no evidence of structural faults such as fatigue, corrosion, or mechanical damage that could have caused the in-flight breakup. 27, p. 92, Trace amounts of explosive residue were detected on three samples of material from three separate locations of the recovered airplane wreckage (described by the FBI as a piece of canvas-like material and two pieces of a floor panel). Flight Engineer/Check Airman Campbell had 3,047 flight hours, including 2,397 of them on the Boeing 747 and was seated in the cockpit jump seat. [36][37][38], Grief turned to anger at TWA's delay in confirming the passenger list,[33] conflicting information from agencies and officials,[39]:1 and mistrust of the recovery operation's priorities. [1]:8789 None of these contacts intersected TWA 800's position at any time. could have biased interviewees' responses in some cases. Purvis says while four years is a long time for an investigation, its not outside the accepted bounds. [1]:279, Although the NTSB had already reached the conclusion that a missile strike did not cause the structural failure of the airplane, the possibility that a missile could have exploded close enough to TWA800 for a missile fragment to have entered the CWT and ignited the fuel/air vapor, yet far enough away not to have left any damage characteristic of a missile strike, was considered. He had 17,000 flight hours, with more than 4,700 of them on the Boeing 747. The four-year investigation into what caused the crash of Trans World Airlines Flight 800 was the longest, and at $40 million, the priciest in the history of the National Transportation Safety Board. By Evan Thomas On 7/28/96 at 8:00 PM EDT. [1]:fig. I made two visits to the mockup the NTSB assembled from the wreckage in a hangar on Long Island at the time, he says. ''I would not want to read the autopsy of my loved one,'' Dr. Wetli said in an interview. [1]:256 This, together with the distribution of wreckage and witness reports, all indicated a sudden catastrophic in-flight breakup of TWA 800. Seventeen of the 18 crew members[20] and 152 of the passengers were Americans; the remaining crew member was Italian, while the remaining passengers were of various other nationalities. In the case of the 747-100 series, the only wiring located inside the CWT is that associated with the FQIS. They ask whether they smoked, since teeth would reflect tobacco stains, and whether they had moles and where. But one customer said the motives are far more complicated. [1]:274, The NTSB also investigated whether the fuel-air mixture in the CWT could have been ignited by lightning strike, meteor strike, auto ignition or hot surface ignition, a fire migrating to the CWT from another fuel tank via the vent system, an uncontained engine failure, a turbine burst in the air conditioning packs beneath the CWT, a malfunctioning CWT jettison/override pump, a malfunctioning CWT scavenger pump, or static electricity. Two Coast Guard crew members who spent two days and nights pulling bodies from the ocean were so traumatized by what they had seen and touched that they were in serious emotional distress, according to local watermen who know them. The FQIS on Flight 800 is known to have been malfunctioning; the captain remarked on "crazy" readings from the system about 2 minutes and 30 seconds before the aircraft exploded. All 230 people on board died in the crash. Of the 230 passengers and crew believed killed in the crash of TWA Flight 800, searchers have found 100 bodies so far, and the Suffolk County medical examiner's office . HAUPPAUGE, New York (CNN) -- The Suffolk County medical examiner has released the first autopsy report on the victims from TWA Flight 800. Six months into the investigation, the NTSB's chairman, Jim Hall, was quoted as saying, "All three theoriesa bomb, a missile, or mechanical failureremain. Trans World Airlines Flight 800 ( TWA800) was a Boeing 747-100 that exploded and crashed into the Atlantic Ocean near East Moriches, New York, on July 17, 1996, at about 8:31 pm. [1]:272 Computer simulations using missile performance data simulated a missile detonating in a location such that a fragment from the warhead could penetrate the CWT. No nothing. [18] Many witnesses in the vicinity of the crash stated that they saw or heard explosions, accompanied by a large fireball or fireballs over the ocean, and observed debris, some of which was burning while falling into the water. The rule required airlines to pump inert gas into the tanks. Flight 800 Autopsy Reports Are Given to Victims' Families, https://www.nytimes.com/1997/01/04/nyregion/flight-800-autopsy-reports-are-given-to-victims-families.html. It was one of the two or three most complex accidents I was involved with during my 17 years doing that kind of workin fact, it may have been the most complicated, he says. [44]:6 After the FBI raised concerns about nongovernmental parties in the NTSB's investigation having access to this information and possible prosecutorial difficulties resulting from multiple interviews of the same witness,[44]:6 the NTSB deferred and did not interview witnesses to the crash. The coroner who oversaw the autopsies on most of the victims of T.W.A. Results: All 230 passengers of TWA Flight 800 were recovered as fatalities. Maintenance records indicate that the aircraft had numerous VSO-related maintenance writeups in the weeks before the accident. [1]:293294 This was not considered proof of a source of ignition. After the 1996 crash of TWA flight 800 off Long Island,. First autopsy report released from TWA 800 crash - January 3, 1997. Twice a week we compile our most fascinating features and deliver them straight to you. [1]:63 This facility became the command center and headquarters for the investigation. TWA 800 then received a series of heading changes and generally increasing altitude assignments as it climbed to its intended cruising altitude. "It's a matter of sensitivity," she said. The new statutory language and the MOU have improved coordination between the NTSB and FBI since the TWA flight 800 accident. In April 1998, the FBI provided the NTSB with the identities of the witnesses, but due to the time elapsed, a decision was made to rely on the original FBI documents rather than reinterview witnesses. [44]:10 With access to these documents no longer controlled by the FBI, the NTSB formed a second witness group to review the documents. And no one is very comfortable going there, so close to the place where that happened, and just sitting and relaxing and playing volleyball."

[1]:109,263 Shortly after, the left wing separated from what remained of the main fuselage, which resulted in further development of the fuel-fed fireballs as the pieces of wreckage fell to the ocean. ", Later in the day, a second dentist emerged from the medical examiner's office and talked with composure about having helped identify his colleague. [1]:258 Of the 5% of the fuselage that was not recovered, none of the missing areas was large enough to have covered all the damage that would have been caused by the detonation of a bomb or missile. ``I don't think anybody was conscious as they fell from 13,000 feet to the water. [1]:123 Because the research data regarding quenching were limited, a complete understanding of quenching behavior was not possible, and the issue of quenching remained unresolved. The . [66] After the TWA flight 800 investigation, the NTSB recognized the need for better clarity. [49]:29 An overpressure event was defined as a rapid increase in pressure resulting in failure of the structure of the CWT.

Dr. Wetli began releasing them this week, saying the families had to contact him in writing to obtain the documents. [68][non-primary source needed], Heidi Snow, the fiance of Flight 800 victim Michel Breistroff, established the AirCraft Casualty Emotional Support Services nonprofit group together with families of victims of Pan Am Flight 103. [56] In 2014, the NTSB declined the petition to reopen the investigation. [41]:1 The FBI, from the start assuming that a criminal act had occurred,[41]:3 saw the NTSB as indecisive. According to WNYC, on July 17, 1996, the doomed Trans World Airlines (TWA) Flight 800 Boeing 747-131 jetliner was heading from New York City towards Paris, and was scheduled to stop there before continuing on to its final destination in Rome.
