[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. [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. A plastic bomb would not leave such traces, he emphasized. But for men and women untrained in dealing with trauma -- a group that includes thousands of vacationers who had come to this area for rest and restoration -- the pain of the crash is much harder to bear. "We can empathize and feel sorry for the families, but we still have a job to do. ", Later in the day, a second dentist emerged from the medical examiner's office and talked with composure about having helped identify his colleague. These tests simulated a fuel-air explosion in the CWT by igniting a propane-air mixture; this resulted in the failure of the tank structure due to overpressure. In this case, the victim was a Long Island dentist who had assisted forensic dentists in the medical examiner's office. 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. The website of The New York Times had its traffic increase to 1.5 million views per day, 50% higher than its previous rate. From Coast Guard crews who became physically ill as waves tossed their search boat to doctors performing autopsies and X-rays in an atmosphere described by one as "a horror movie turned real," the toll of the Flight 800 disaster became increasingly vivid today on its behind-the-scenes players. Dr. Charles V. Wetli, the Suffolk County Medical. Or purchase a subscription for unlimited access to real news you can count on. [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. [5] Sixteen months later, the JTTF announced that no evidence of a criminal act had been found and closed its active investigation. On July 24, 2012, this FOIA release was re-uploaded to address technical issues. - Administrative Policy Procedures -Anti-War -Bureau Personnel -Civil Rights -Counterterrorism -Foreign Counterintelligence- Frequently Requested -Fugitives -Gangs Extremist Groups -Gangster Era -Miscellaneous -Organizations -Organized Crime -Political Figures Events -Popular Culture -Public Corruption -Supreme Court -Unexplained Phenomenon -World War II -Violent Crime. [1]:94 Additionally, the occupants of the target track were unlikely to have been able to hear the explosions over the sound of its engines and the noise of the hull traveling through water, even more so if the occupants were in an enclosed bridge or cabin. [1]:263, Only the FAA radar facility in North Truro, Massachusetts, using specialized processing software from the United States Air Force 84th Radar Evaluation Squadron, was capable of estimating the altitude of TWA 800 after it lost power due to the CWT explosion. "You get a little used to it," he said. [1]:273, Similarly, the investigation considered the possibility that a small explosive charge placed on the CWT could have been the ignition source. [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). Many recommendations came out of the completed investigation, including everything from changes in daily operational procedures to modifications of the center fuel tanks on other 747s, Oakley says. CAPTION: On a dock in Brooklyn, a section of the 747 jumbo jet that crashed Wednesday night is hauled away as part of the investigation into the cause. The FBI may still conduct a criminal investigation, but the NTSB investigation has priority. Investigators believe the explosion began in the center fuel tank, but they say. [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. A safety board investigator later reviewed FBI interview notes and briefed other board investigators on their contents. Although it could not be determined with certainty, the likely ignition source was a short circuit. 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. [1]:262, Thirty-eight witnesses described a streak of light that ascended vertically, or nearly so, and these accounts "seem[ed] to be inconsistent with the accident airplane's flightpath. [1]:94 Further, review of the Islip radar data for other similar summer days and nights in 1999 indicated that the 30-knot track was consistent with normal commercial fishing, recreational, and cargo vessel traffic. [1]:87 Because of accuracy limitations, these radar data could not be used to determine whether the aircraft climbed after the nose separated. Expressing frustration at the NTSB's unwillingness to speculate on a cause, one FBI agent described the NTSB as "No opinions. 26, p. 91, Primary radar returns that appeared near the TWA 800 after 8:31:12pm: The 30-knot track is at the bottom center of the image. [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. J. Conrad Williams Jr./Newsday RM via Getty Images. 1. News. [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 NTSB was never able to pin-point the precise cause, but it was clear that it was from within the tank.. 22a, p. 66, Wreckage found in each zone corresponded to specific areas of the aircraft[1]:fig. But even though we're physicians, we're still human. 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. [29] In the case of TWA 800, the FBI initiated a parallel criminal investigation alongside the NTSB's accident investigation. According to Purvis, the safety board addressed the missile idea in its report. Speculation fueled theories that a terrorist act had caused the crash that killed the 230 on board, but an investigation later concluded it was a tragic mechanical error. [1]:63 This facility became the command center and headquarters for the investigation. 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. [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. He said the bodies will be identified through medical records and interview materials. [66] After the TWA flight 800 investigation, the NTSB recognized the need for better clarity. On July 7, 2021, 25 years following the crash, the NTSB will decommission the wreckage, which will be destroyed by the end of 2022. Recovery workers searching the wreckage of Trans World Airlines Flight 800 found the bodies of dozens of victims of the crash yesterday in a large area of debris on the ocean floor off Long Island. [1]:258, The NTSB considered the possibility that the explosive residue was due to contamination from the aircraft's use in 1991 transporting troops during the Gulf War or its use in a dog-training explosive detection exercise about one month before the accident. [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. By Evan Thomas On 7/28/96 at 8:00 PM EDT. The lighthouse statue was designed by Harry Edward Seaman, whose cousin died in the crash, and dedicated by George Pataki. The event remains one of the deadliest plane crashes in U.S. history. [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. According to Oakley, the 25 years following the tragic Flight 800 crash have included the safest years in U.S. commercial aviation history. 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. The tortuous search for bodies and plane remnants was delayed as rain, wind and fog rendered the Atlantic impassable for search crews. [1]:288 Arcing signs were also seen on two wires sharing a cable raceway with FQIS wiring at station 955. That added some time to the investigation.. July 22, 1996 12 AM PT. [1]:9697 These simulations indicated that after the loss of the forward fuselage the remainder of the aircraft continued in crippled flight, then pitched up while rolling to the left (north),[1]:263 climbing to a maximum altitude between 15,537 and 16,678 feet (4,736 and 5,083m)[1]:97 from its last recorded altitude, 13,760 feet (4,190m). 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]:288. When the rare fatal air accident occurs it usually involves a causality chain, including a number of seemingly unconnected small anomalies that, together, create a sort of perfect storm which causes a crash, he says. [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. [1]:93 All the reviewed radar data showed no radar returns consistent with a missile or other projectile traveling toward TWA 800. [1]:293294 This was not considered proof of a source of ignition. [1]:258 This included the pieces on which trace amounts of explosives were found. 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. Hundreds of witnesses saw the plane explode from . [1]:256 This, together with the distribution of wreckage and witness reports, all indicated a sudden catastrophic in-flight breakup of TWA 800. Captain/Check Airman Snyder was seated in the first officer's (right) seat monitoring Kevorkian's progress. [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. "[1]:2 A loud noise recorded on the last few tenths of a second of the CVR was similar to the last noises recorded from other airplanes that had experienced in-flight breakups. could have biased interviewees' responses in some cases. And no one is very comfortable going there, so close to the place where that happened, and just sitting and relaxing and playing volleyball." [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. [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". [44]:5, Around 80 FBI agents conducted interviews with potential witnesses daily. Funds for the memorial were raised by the Families of TWA Flight 800 Association. In July 2006, an abstract black granite statue of a 10-foot-high (3.0m) lighthouse was added above a tomb holding many of the victims' personal belongings. 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]:313 Meanwhile, initial witness descriptions led many to believe the cause of the crash was a bomb or surface-to-air missile attack. "It's a matter of sensitivity," she said. ''They are very cold, chilling documents,'' he said. [1]:272279 After analysis, the investigation determined that these potential sources were "very unlikely" to have been the source of ignition. and "How long did the missile fly?" [1]:1 All 230 people on board died in the crash; it is the third-deadliest aviation accident in U.S. history. I saw none, and the real experts, who were much better at it than I, saw nothing either. 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. Flight engineer trainee Krick was seated in the flight engineer's seat (being monitored by Flight Engineer/Check Airman Campbell); he was the least experienced of the crew, having logged 2,520 flight hours, but with only 30 of them on the Boeing 747. TWA 800 then received a series of heading changes and generally increasing altitude assignments as it climbed to its intended cruising altitude.
