Dr. Wetli said he had delayed releasing the documents because the crash was potentially a criminal case and he did not want to do anything to jeopardize the investigation. [1]:293294 This was not considered proof of a source of ignition. Taxi and takeoff proceeded uneventfully. The aircraft had completed 16,869 flights with 93,303 hours of operation and was powered by four Pratt & Whitney JT9D-7AH turbofan engines. This article incorporates public domain material from websites or documents of the National Transportation Safety Board. [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. TWA Flight 800 was en route from New York to Paris when it exploded over Long Island Sound minutes after takeoff. Anyone can read what you share. [1]:31. These records range from 1996 to 1998 and concern FBI forensic analysis associated with the Bureaus crash investigation. [44]:78, In February 1998, the FBI, having closed its active investigation, agreed to fully release the witness summaries to the NTSB. They ask about shoe size and even type of shoes, since some victims were found with shoes still on. Death On Flight 800. TWA Flight 800 crashed eight miles off the coast of Long Island at dusk on a clear summer night. So the appearance of a missile was basically an optical illusion..

[14] During refueling of the aircraft, the volumetric shutoff (VSO) control was believed to have been triggered before the tanks were full. The report on passenger Susan Hill, a homicide. [1]:58 The victims' remains were transported to the Suffolk County Medical Examiner's Office in Hauppauge, New York. [1]:fig. Fuel-air explosion in the center wing fuel tank, In-flight breakup sequence and crippled flight, Analysis of reported witness observations, Possible ignition sources of the center wing fuel tank, Missile fragment or small explosive charge. Investigators believe the explosion began in the center fuel tank, but they say. [1]:7174, Pieces of wreckage were transported by boat to shore and then by truck to leased hangar space at the former Grumman Aircraft facility in Calverton, New York, for storage, examination, and reconstruction. Pathologists are meeting daily with family members, conducting interviews about minute details of the victims' bodies to help determine who is who. 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 . 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]:279, Because a combustible fuel-air mixture will always exist in fuel tanks, Boeing designers had attempted to eliminate all possible sources of ignition in the 747's tanks. 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. July 22, 1996 12 AM PT. The investigation of the crash of T.W.A. [1]:4 The last radio transmission from the airplane occurred at 8:30pm, when the flight crew received and then acknowledged instructions from Boston Center to climb to 15,000 feet (4,600m). could have biased interviewees' responses in some cases. Instead, he said, there are blunt force trauma injuries, consistent with being struck by pieces of the jet as it fell from the sky after an explosion elsewhere in the plane. [54]:6. The FBI's earliest investigations and interviews, later used by the NTSB, were performed under the assumption of a missile attack, a fact noted in the NTSB's final report. On June 19, 2013, the NTSB acknowledged in a press release that they received a petition for reconsideration of its investigation into the July 17, 1996, crash of TWA Flight 800. [51]:6, As the investigation progressed, the NTSB decided to form a witness group to more fully address the accounts of witnesses. So far, only a couple of families have received the reports, and Dr. Wetli declined to give specifics. He said it was likely that death for the passengers was instantaneous. But James K. Kallstrom, who is heading the criminal arm of the investigation for the Federal Bureau of Investigation, told the Medical Examiner last week that he had no objection to the release of the autopsy reports to the next of kin. No nothing. [1]:6574 The green zone with the aft portion of the aircraft was located the furthest along the flight path. The aircraft was refueled, and a crew change was made; the new flight crew consisted of 58-year-old Captain Ralph G. Kevorkian (who had flown for TWA for 31 years and the U.S. Air Force for 9 years), 57-year-old Captain/Check Airman Steven E. Snyder (who had flown for TWA for 32 years), and 63-year-old Flight Engineer/Check Airman Richard G. Campbell Jr. (who had flown for TWA for 30 years and the U.S. Air Force for 12 years), as well as 25-year-old flight engineer trainee Oliver Krick (who previously served as a business pilot for 4 years), who had flown for TWA for 26 days and was starting the sixth leg of his initial operating experience training. [1]:261, Ultimately, based on "the accident airplane's breakup sequence; wreckage damage characteristics; scientific tests and research on fuels, fuel tank explosions, and the conditions in the CWT at the time of the accident; and analysis of witness information,"[1]:271 the NTSB concluded that "the TWA flight 800 in-flight breakup was initiated by a fuel/air explosion in the CWT. Plus, investigators applied extra diligence to accommodate a huge amount of pressure applied from many quarters to make absolutely sure this was not the result of a terrorist operation, or an errant missile fired by our, or some other nations, military.. Almost immediately there was speculation that the plane had been the target of a terrorist attack, with many claiming theyd spotted what appeared to be a missile heading toward the plane just before it exploded. [1]:3 [1]:100 In addition, the locations of pieces of wreckage at the time of recovery and differences in fire effects on pieces that are normally adjacent to each other were evaluated. Flight 800 was actually a training flight for Kevorkian, and he was seated in the captain's (left) seat. 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. The FBI interviewed at least 755 witnesses. ", Later in the day, a second dentist emerged from the medical examiner's office and talked with composure about having helped identify his colleague. Funds for the memorial were raised by the Families of TWA Flight 800 Association. Flight 800 lawsuit puts focus on fuel pump - Dec . [41]:1 The FBI, from the start assuming that a criminal act had occurred,[41]:3 saw the NTSB as indecisive. In the early days and weeks after the accident, the FBI was in charge because there was concern about it being a crime. "[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]:xvi Problems with the aircraft's wiring were found, including evidence of arcing in the fuel quantity indication system (FQIS) wiring that enters the tank. 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. Below is a list of those on board, according to family, friends or officials . 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. All Rights Reserved. FACT CHECK: We strive for accuracy and fairness. Maintenance records indicate that the aircraft had numerous VSO-related maintenance writeups in the weeks before the accident. The rule covered the CWT on all new passenger and cargo airliners, and passenger planes built in most of the 1990s, but not old cargo planes. [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. [7][8] The report's conclusion was that the probable cause of the accident was explosion of flammable fuel vapors in the center fuel tank. "The explosion that occurred on TWA 800 was in the center wing fuel tank and was not from anything external," he says. [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. EDT, 12 minutes after takeoff from John F. Kennedy International Airport, on a scheduled international passenger flight to Rome, with a stopover in Paris. [1]:3 Intense public interest arose in these witness reports, as did much speculation that the reported streak of light was a missile that had struck TWA 800, causing the airplane to explode. The NTSB found that the probable cause of the crash of TWA Flight 800 was an explosion of flammable fuel/air vapors in a fuel tank, most likely from a short circuit. 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. The NTSB sought and secured language[citation needed] to clarify the issue in 49 USC 1131(a)(2)(B), which was amended in 2000 to read: .mw-parser-output .quotebox{background-color:#F9F9F9;border:1px solid #aaa;box-sizing:border-box;padding:10px;font-size:88%;max-width:100%}.mw-parser-output .quotebox.floatleft{margin:.5em 1.4em .8em 0}.mw-parser-output .quotebox.floatright{margin:.5em 0 .8em 1.4em}.mw-parser-output .quotebox.centered{overflow:hidden;position:relative;margin:.5em auto .8em auto}.mw-parser-output .quotebox.floatleft span,.mw-parser-output .quotebox.floatright span{font-style:inherit}.mw-parser-output .quotebox>blockquote{margin:0;padding:0;border-left:0;font-family:inherit;font-size:inherit}.mw-parser-output .quotebox-title{background-color:#F9F9F9;text-align:center;font-size:110%;font-weight:bold}.mw-parser-output .quotebox-quote>:first-child{margin-top:0}.mw-parser-output .quotebox-quote:last-child>:last-child{margin-bottom:0}.mw-parser-output .quotebox-quote.quoted:before{font-family:"Times New Roman",serif;font-weight:bold;font-size:large;color:gray;content:" ";vertical-align:-45%;line-height:0}.mw-parser-output .quotebox-quote.quoted:after{font-family:"Times New Roman",serif;font-weight:bold;font-size:large;color:gray;content:" ";line-height:0}.mw-parser-output .quotebox .left-aligned{text-align:left}.mw-parser-output .quotebox .right-aligned{text-align:right}.mw-parser-output .quotebox .center-aligned{text-align:center}.mw-parser-output .quotebox .quote-title,.mw-parser-output .quotebox .quotebox-quote{display:block}.mw-parser-output .quotebox cite{display:block;font-style:normal}@media screen and (max-width:640px){.mw-parser-output .quotebox{width:100%!important;margin:0 0 .8em!important;float:none!important}}, If the Attorney General, in consultation with the Chairman of the [NTSB], determines and notifies the [NTSB] that circumstances reasonably indicate that the accident may have been caused by an intentional criminal act, the [NTSB] shall relinquish investigative priority to the [FBI]. 1. It is fair to say that we will never see another accident of this kind involving this aircraft type. [1]:2 Weather in the area was light winds with scattered clouds,[1]:256 with dusk lighting conditions. [1]:93 In addition, the records indicated that the closest area scheduled for military use, warning area W-387A/B, was 160 nautical miles (296km; 184mi) south. [1]:87 Instead, the NTSB conducted a series of computer simulations to examine the flightpath of the main portion of the fuselage. [1]:266 The NTSB concluded that given the large number of witnesses in this case, they "did not expect all of the documented witness observations to be consistent with one another"[1]:269 and "did not view these apparently anomalous witness reports as persuasive evidence that some witnesses might have observed a missile. [1]:258259 Testing conducted by the FAA's Technical Center indicated that residues of the type of explosives found on the wreckage would dissipate completely after two days of immersion in sea water (almost all recovered wreckage was immersed longer than two days). [66] After the TWA flight 800 investigation, the NTSB recognized the need for better clarity. But one customer said the motives are far more complicated. Each agency can call upon the other's laboratories and other assets. He says fatal incidents tend to occur when an airplane is unintentionally flown into violent weather, usually a thunderstorm or, very rarely, some form of severe clear air turbulence (CAT). Purvis says while four years is a long time for an investigation, its not outside the accepted bounds. [1]:256, Investigators considered several possible causes for the structural breakup - structural failure and decompression, detonation of a high-energy explosive device, such as a missile warhead exploding either upon impact with the airplane, or just before impact, a bomb exploding inside the airplane, or a fuel-air explosion in the center wing fuel tank. Trans World Airlines Flight 800 was carrying 230 people, including four cockpit crew members and 14 flight attendants. Only 15 of the 230 bodies have not been recovered. 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. "We can empathize and feel sorry for the families, but we still have a job to do. [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". The new statutory language and the MOU have improved coordination between the NTSB and FBI since the TWA flight 800 accident. [31]:3[41]:5[39]:12 Under constant and considerable pressure to identify victims with minimal delay,[32]:3 pathologists worked nonstop. Although it could not be determined with certainty, the likely ignition source was a short circuit. [specify] The agencies lacked a detailed protocol describing which agency should take the lead when whether an event was an accident or a criminal act was initially unclear. 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. So losing Flight 800 to an in-flight explosion of another kind was a very rare event indeed.. When investigative priority remains with the NTSB, the FBI must coordinate its investigative activities with the NTSB investigator-in-charge. CAPTION: A flower shop sign on Highway 25 outside East Moriches carries sentiments felt by many along the south shore of Long Island, closest land to crash site. According to commercial aviation historian Shea Oakley, NTSB investigations are almost never short-term affairs. [1]:258 None of the victims' remains showed any evidence of injuries that could have been caused by high-energy explosives. 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. The NTSB and the FBI have designated liaisons to ensure that information flows between agencies, and to coordinate on-scene operations. Accident investigators from the National Transportation Safety Board (NTSB) traveled to the scene, arriving the following morning[1]:313 amid speculation that a terrorist attack was the cause of the crash. Thus, the gauge anomaly could have been caused by a short to the FQIS wiring. Or purchase a subscription for unlimited access to real news you can count on. Six months into the investigation, the NTSB's chairman, Jim Hall, was quoted as saying, "All three theoriesa bomb, a missile, or mechanical failureremain. To report an incident/accident or if you are a public safety agency, please call 1-844-373-9922 or 202-314-6290 to speak to a Watch Officer . What many thought was a missile was actually the death throes of an airplane that briefly went up before it, sadly and inevitably, went down, Oakley says. [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. [1]:257 The NTSB concluded that "the in-flight breakup of TWA flight 800 was not initiated by a pre-existing condition resulting in a structural failure and decompression. In this case, the victim was a Long Island. [1]:363365 An HH-60 Pave Hawk helicopter of the New York Air National Guard saw the explosion from about 8 miles away; it arrived at the scene of the explosion while debris was still in the process of falling into the water, forcing the crew to pull away. [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. [1]:258 This included the pieces on which trace amounts of explosives were found. ")[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. First autopsy report released from TWA 800 crash - January 3, 1997. [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. 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]: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. [1]:3, Thirty-eight seconds later, the captain of an Eastwind Airlines Boeing 737 reported to Boston ARTCC that he "just saw an explosion out here", adding, "we just saw an explosion up ahead of us here about 16,000 feet [4,900m] or something like that, it just went down into the water. TWA's senior management had spent Wednesday celebrating in London. New York's Pataki asks feds to help pay for TWA recovery - December 27, 1996. Air travel safety, in general, has steadily improved since the beginning of the widespread use of jet aircraft in 1958, he says. [1]:89 Attention was drawn to data from the Islip, New York, ARTCC facility that showed three tracks in the vicinity of TWA 800 that did not appear in any of the other radar data. Medical Examiner Wetli said only half of the 100 bodies retrieved from the ocean so far had been processed, meaning photographed, fingerprinted, weighed, X-rayed, and autopsied. Twice a week we compile our most fascinating features and deliver them straight to you. [1]:264, The NTSB concluded, "the witness observations of a streak of light were not related to a missile and that the streak of light reported by most of these witnesses was burning fuel from the accident airplane in crippled flight during some portion of the postexplosion, preimpact breakup sequence". [1]:261 While the NTSB acknowledged that the test conditions at Bruntingthorpe were not fully comparable to the conditions that existed on TWA 800 at the time of the accident,[1]:261 previous fuel explosions in the CWTs of commercial airliners such as Avianca Flight 203 and Philippine Airlines Flight 143 confirmed that a CWT explosion could break apart the fuel tank and lead to the destruction of an airplane. By 2021, the methods taught using the wreckage were determined to no longer be relevant to modern accident investigation, which by then relied heavily on new technology, including three-dimensional laser-scanning techniques. I spent a fair amount of time examining the wreckage, looking for signs of missile/projectile entry. MOST of the 230 people aboard TWA Flight 800 were killed quickly in mid air by "phenomenal whiplash" when the plane exploded, Tue Aug 20 1996 - 01:00 MOST of the 230 people aboard TWA. [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. January 3, 1997. However, because of the previous maintenance undertaken on engine #3, the flight crew only started engines #1, #2, and #4. In addition, it restricts lawyers and other parties from contacting family members within 30 days of the accident. [41]:5 Since the primary objective was to identify all remains rather than performing a detailed forensic autopsy, the thoroughness of the examinations was highly variable. 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). A 3-D scan of the reconstruction will be made for historical record. "[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.
