86-609: In July 1995, the jail, initially the Atascocita State Jail , opened. After Pam Lychner , a victim's rights activist, died on board TWA Flight 800 with her daughters on July 17, 1996, the TDCJ board unanimously voted to rename the facility to Pam Lychner State Jail . The Pam Lychner State Jail, along with the Joe Kegans State Jail , serves state jail offenders from Harris County. Lychner and Kegans have

172-564: A CWT explosion could break apart the fuel tank and lead to the destruction of an airplane. 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," the NTSB concluded that "the TWA flight 800 in-flight breakup

He plea bargained and received a sentence of 20 years for "aggravated kidnapping with intent to commit sex assault." After the Texas Department of Criminal Justice (TDCJ) sent a letter to the Lychner residence, notifying the household that the state nominated Kelley as a candidate for early release, Lychner decided to become an advocate for victim's rights, founding

430-493: A flammable mixture of air and aviation fuel vapors in the center wing fuel tank exploded, destroying the aircraft. After Pam, Shannon, and Katie died, the United States Congress passed the "Pam Lychner Sexual Offender Tracking and Identification Act of 1996." On July 15, 1997, Spring Valley Village dedicated a bronze statue of her, Shannon, and Katie, called "Love's Embrace," at the city hall. After it

516-420: A fuel-air explosion in the CWT. There were 50 US gal (190 L) of fuel in the CWT of TWA 800; tests recreating the flight conditions showed the combination of liquid fuel and fuel-air vapor to be flammable. A major reason for the flammability of the fuel-air vapor in the CWT of the 747 was the large amount of heat generated and transferred to the CWT by air-conditioning packs located directly below

602-528: A high-energy explosion of a bomb or missile warhead ("severe pitting, cratering, petalling or hot-gas washing"). This included the pieces on which trace amounts of explosives were found. Of the 5% of the fuselage that was not recovered, none of the missing areas was large enough to have covered all of the damage that would have been caused by the detonation of a bomb or missile. None of the victims' remains showed any evidence of injuries that could have been caused by high-energy explosives. The NTSB considered

688-614: A limited number of witness interviews. In April 1998, the FBI provided the NTSB with the identities of the witnesses, but because of the time that had elapsed, a decision was made to rely on the original FBI documents rather than on reinterviewed witnesses. Examination of the cockpit voice recorder (CVR) and flight data recorder data showed a normal takeoff and climb, with the aircraft in normal flight before both abruptly stopped at 8:31:12 p.m. At 8:29:15 p.m., Captain Kevorkian

774-543: A missile." After missile visibility tests were conducted in April 2000, at Eglin Air Force Base , Fort Walton Beach, Florida , the NTSB determined that if witnesses had observed a missile attack, they would have seen: Because of their unique vantage points or the level of precision and detail provided in their accounts, five witness accounts generated special interest: the pilot of Eastwind Airlines Flight 507,

860-551: A retired Air France 747 at Bruntingthorpe Airfield , England. These tests simulated a fuel-air explosion in the CWT by igniting a propane-air mixture, which failed the tank structure from overpressure. While the NTSB acknowledged that the test conditions at Bruntingthorpe were not fully comparable to the conditions that existed on TWA 800, previous fuel explosions in the CWTs of commercial airliners such as those of Avianca Flight 203 and Philippine Airlines Flight 143 confirmed that

946-557: A structural failure and decompression." A review of recorded data from long-range and airport surveillance radars revealed multiple contacts of airplanes or objects in TWA ;800's vicinity at the time of the accident. None of these contacts intersected TWA 800's position at any time. 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

1032-639: A three-day trip. Pam, Shannon, and Katie flew from Houston to John F. Kennedy International Airport in New York City , and then connected to TWA Flight 800 bound for Charles de Gaulle International Airport near Paris, on July 17, 1996. N93119, the Boeing 747-100 used for Flight 800, exploded off the coast of Long Island , killing all of the passengers and crew, including the three Lychners. Joe advocated for an investigation of Flight 800. According to him, Pam's and Katie's bodies were recovered during

1118-611: The Boeing 747-100 serving the flight exploded and crashed into the Atlantic Ocean near East Moriches, New York . All 230 people on board died in the crash; it is the third-deadliest aviation accident in U.S. history. Accident investigators from the National Transportation Safety Board (NTSB) traveled to the scene, arriving the following morning amid speculation that a terrorist attack

1204-484: 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. Because of accuracy limitations, these radar data could not be used to determine whether the aircraft climbed after the nose separated. Instead, the NTSB conducted a series of computer simulations to examine the flightpath of the main portion of

1290-464: The CWT. Because the research data regarding quenching were limited, a complete understanding of quenching behavior was not possible, and the issue of quenching remained unresolved. To better determine whether a fuel-air vapor explosion in the CWT would generate sufficient pressure to break apart the fuel tank and lead to the destruction of the airplane, tests were conducted in July and August 1997 using

1376-461: 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. In February 1998, the FBI, having closed its active investigation, agreed to fully release the witness summaries to the NTSB. With access to these documents no longer controlled by

1462-424: The FBI, the NTSB formed a second witness group to review the documents. Because of the time that had elapsed (about 21 months) before the NTSB received information about the identity of the witnesses, the witness group chose not to reinterview the witnesses, but instead to rely on the original summaries of witness statements written by FBI agents as the best available evidence of the observations initially reported by

1548-487: The NTSB to relinquish control of the investigation to the FBI. In the case of TWA 800, the FBI initiated a parallel criminal investigation alongside the NTSB's accident investigation. Search-and-recovery operations were conducted by federal, state, and local agencies, as well as by government contractors. Personnel in an HH-60 Pave Hawk helicopter of the New York Air National Guard witnessed

1634-497: The NTSB's investigation having access to this information and possible prosecutorial difficulties resulting from multiple interviews of the same witnesses, the NTSB deferred and did not interview witnesses. A safety board investigator later reviewed FBI interview notes and briefed other board investigators on their contents. In November 1996, the FBI agreed to allow the NTSB access to summaries of witness accounts in which personally identifying information had been redacted and to conduct

1720-420: The NTSB's unwillingness to speculate on a cause, one FBI agent described the NTSB as "No opinions. No nothing." Meanwhile, the NTSB was required to refute or minimize speculation about conclusions and evidence, frequently supplied to reporters by law-enforcement officials and politicians. The International Association of Machinists and Aerospace Workers , an invited party to the NTSB investigation, criticized

1806-493: The New York/ Long Island area received reports of an explosion from other pilots operating in the area. 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. Various civilian, military, and police vessels reached the crash site within minutes of

1892-558: The TDCJ board unanimously voted to rename it after her. A duplicate of the statue in Spring Valley Village exists near it. TWA Flight 800 Trans World Airlines Flight 800 ( TW800/TWA800 ) was a scheduled international passenger flight from New York ( John F. Kennedy International Airport ) to Rome , with a stopover in Paris . On July 17, 1996, at approximately 8:31   p.m. EDT , 12 minutes after takeoff,

Also with the crew was 25-year-old flight-engineer trainee Oliver Krick, who previously served as a business pilot for four years and had 2,500 flight hours, including 30 on the Boeing 747. Krick had flown for TWA for 26 days and was starting the sixth leg of his initial operating experience training. Flight 800

2064-449: The accident airplane after the CWT explosion. 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." In addition, 18 witnesses reported seeing a streak of light that originated at the surface, or the horizon, which did not "appear to be consistent with the airplane's calculated flightpath and other known aspects of

2150-400: The accident sequence." Regarding these differing accounts, the NTSB noted that based on their experience in previous investigations "witness reports are often inconsistent with the known facts or with other witnesses' reports of the same events." The interviews conducted by the FBI focused on the possibility of a missile attack; suggested interview questions given to FBI agents such as "Where

2236-448: The agents who conducted the interviews wrote summaries that they then submitted. Witnesses were not asked to review or correct the summaries. Included in some of the witness summaries were drawings or diagrams of what the witnesses had observed. Within days of the crash, the NTSB announced its intent to form its own witness group and to interview witnesses to the crash. After the FBI raised concerns about nongovernmental parties in

2322-480: The aircraft, the volumetric shutoff (VSO) control was believed to have been triggered before the tanks were full. To continue the pressure fueling, a TWA mechanic overrode the automatic VSO by pulling the volumetric fuse and an overflow circuit breaker. Maintenance records indicate that the aircraft had numerous VSO-related maintenance writeups in the weeks before the accident. TWA 800 was scheduled to depart JFK for Charles de Gaulle Airport around 7:00 p.m., but

2408-487: The airplane occurred at 8:30 p.m., when the flight crew received and then acknowledged instructions from Boston Center to climb to 15,000 feet (4,600 m). The last recorded radar transponder return from the airplane was recorded by the Federal Aviation Administration (FAA) radar site at Trevose, Pennsylvania , at 8:31:12 p.m. Thirty-eight seconds later, David McClaine,

2494-409: The airplane's burning wreckage falling toward the ocean". To determine what ignited the flammable fuel-air vapor in the CWT and caused the explosion, the NTSB evaluated numerous potential ignition sources. All but one were considered very unlikely to have been the source of ignition. Although the NTSB had already concluded that a missile strike did not cause the structural failure of the airplane,

2580-458: The airplane, respectively. The green zone with the aft portion of the aircraft was located the farthest along the flight path. 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. The facility became the command center and headquarters for

According to the seat manufacturer, the locations and appearance of the substance were consistent with adhesive used in the construction of the seats, and additional laboratory testing by NASA identified the substance as consistent with adhesives. Further examination of the airplane structure, seats, and other interior components found no damage typically associated with

2752-434: The breakup sequence was a fracture in the wing center section of the aircraft caused by an "overpressure event" in the center-wing fuel tank (CWT). An overpressure event was defined as a rapid increase in pressure resulting in failure of the structure of the CWT. Because no evidence was found that an explosive device detonated in this (or any other) area of the airplane, the overpressure event could only have been caused by

2838-424: The captain of Eastwind Airlines Flight 507, operated by Boeing 737-200 N221US ( which had suffered a near-crash of its own a month prior ) 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 [4,900 m] or something like that, it just went down into the water." Subsequently, many air traffic control facilities in

2924-428: 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. Military records examined by the NTSB showed no military surface vessels within 15 nautical miles (28 km; 17 mi) of TWA 800 at the time of the accident. In addition, the records indicated that the closest area scheduled for military use, warning area W-387A/B,

Advocates of a missile-attack scenario asserted that some of these witnesses observed a missile; analysis demonstrated that the observations were not consistent with a missile attack on TWA 800, but instead were consistent with these witnesses having observed part of

3096-496: The exact source of the trace amounts of explosive residue found in the wreckage, the lack of any other corroborating evidence associated with a high-energy explosion led the NTSB to conclude that "the in-flight breakup of TWA flight 800 was not initiated by a bomb or missile strike." To evaluate the sequence of structural breakup of the airplane, the NTSB formed the Sequencing Group, which examined individual pieces of

3182-534: The explosion from about eight miles (13 km) away and arrived at the scene of the explosion while debris was still falling into the water, forcing the crew to retreat. They reported their sighting to the tower at Suffolk County Airport . Remotely operated vehicles (ROVs), side-scan sonar and laser line-scanning equipment were employed to search for and investigate underwater debris fields. Victims and wreckage were recovered by scuba divers and ROVs. Later, scallop trawlers were used to recover wreckage embedded in

3268-488: The first night of rescue efforts. On July 22, five days after the crash, the Suffolk County, New York coroners had identified Pam's body, and he was summoned to confirm the identification. Days later Katie's body was positively identified, and on July 28 Shannon's body was recovered. All three received burial in a family plot near Chicago, Illinois . The National Transportation Safety Board (NTSB) concluded that

TWA 800 then received a series of heading changes and generally increasing altitude assignments as it climbed to its intended cruising altitude. Weather in the area was light winds with scattered clouds, with dusk lighting conditions. The last radio transmission from

After the owner of the baggage in question was confirmed to be on board, the flight crew prepared for departure, and the aircraft pushed back from Gate 27 at the TWA Flight Center . The flight crew started the engines at 8:04 p.m. However, because of the previous maintenance undertaken on engine No. 3,

The FQIS on Flight 800 is known to have been malfunctioning; the captain remarked about "crazy" readings from the system about two minutes and 30 seconds before the aircraft exploded. As a result of the investigation, new requirements were developed for aircraft to prevent future fuel-tank explosions . The accident airplane, registration N93119 (a Boeing 747-131 ),

3612-461: The fuselage. Hundreds of simulations were run using various combinations of possible times the nose of TWA 800 separated (the exact time was unknown), different models of the behavior of the crippled aircraft (the aerodynamic properties of the aircraft without its nose could only be estimated), and longitudinal radar data (the recorded radar tracks of the east/west position of TWA 800 from various sites differed). These simulations indicated that after

Lychner promoted and, according to U.S. Senators Phil Gramm and Joe Biden , crafted

3784-486: The in-flight breakup. The breakup could have been initiated by an in-flight separation of the forward cargo door as had occurred in the Turkish Airlines Flight 981 or United Airlines Flight 811 accidents, but all evidence indicated that the door was closed and locked at impact. The NTSB concluded that "the in-flight breakup of TWA flight 800 was not initiated by a pre-existing condition resulting in

3870-456: The in-flight fire and breakup sequence after the CWT explosion. 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". The NTSB further concluded, "the witnesses' observations of one or more fireballs were of

They searched for survivors but found none, making TWA 800 the second-deadliest aircraft accident in United States history at that time, only exceeded by American Airlines Flight 191 . On board TWA 800 were 230 people, including 18 crew and 20 off-duty employees, most of whom were crew meant to cover the Paris-Rome leg of the flight. Seventeen of the 18 crew members and 152 of

4042-729: The investigation. NTSB and FBI personnel were present to observe all transfers to preserve the evidentiary value of the wreckage. The cockpit voice recorder and flight data recorder were recovered by U.S. Navy divers one week after the accident, and the machines were immediately shipped to the NTSB laboratory in Washington, D.C. for analysis. The victims' remains were transported to the Suffolk County Medical Examiner 's office in Hauppauge, New York . Relatives of TWA 800 passengers and crew, as well as

4128-879: The language of a bill, later called the "Pam Lychner Sexual Offender Tracking and Identification Act of 1996," that established a federal database for United States sex offenders. In addition, the bill required sex offenders who move to new locations to contact authorities; if they fail to do so they face fines and prison sentences. At the time of her death in 1996, Pam was married to Joe, and they had two daughters, 10-year-old Shannon and 8-year-old Katie. They lived in Spring Valley Village, Texas in Greater Houston . Shannon had copied Claude Monet 's paintings, and Pam wanted her to see his former garden, Fondation Monet in Giverny , France . They had planned

4214-434: The loss of the forward fuselage the remainder of the aircraft continued in crippled flight, then pitched up while rolling to the left (north), climbing to a maximum altitude between 15,537 and 16,678 feet (4,736 and 5,083 m) from its last recorded altitude, 13,760 feet (4,190 m). At the start of the FBI's investigation, because of the possibility that international terrorists might have been involved, assistance

4300-574: The loss of the forward fuselage. After about 34 seconds (based on information from witness documents), the outer portions of both the right and left wings failed. 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. Only the FAA radar facility in North Truro , Massachusetts , using specialized processing software from

4472-405: The morgue. Under constant pressure to identify victims with minimal delay, pathologists worked long hours. While some victims' bodies were generally intact, most others were burned, fragmented, skeletonized, or decaying, necessitating identification using DNA testing and dental records. As the primary objective was to identify all remains rather than to perform detailed forensic autopsies,

4558-422: The most extensive, complex, and costly air disaster investigation in U.S. history at that time. The report's conclusion was that the probable cause of the accident was the explosion of flammable fuel vapors in the center fuel tank . Although it could not be determined with certainty, the likely ignition source was a short circuit . Problems with the aircraft's wiring were found, including evidence of arcing in

4644-517: The other radar data. None of these sequences intersected TWA 800's position at any time. None of the reviewed data showed radar returns consistent with a missile or other projectile traveling toward TWA 800. The NTSB addressed allegations that the Islip radar data showed groups of military surface targets converging suspiciously in an area around the accident and that an unidentified 30-knot radar track, 3 nautical miles (5.6 km; 3.5 mi) from

4730-622: The passengers were Americans; the remaining crew member was Italian, while the remaining passengers were of various other nationalities. Notable passengers included: In addition, 16 students and five adult chaperones from the French Club of the Montoursville Area High School in Pennsylvania were on board. The NTSB was notified at approximately 8:50 p.m. on the day of the accident. A full " go team "

4816-411: The possibility that a missile could have exploded close enough to TWA 800 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. Computer simulations using missile performance data simulated a missile detonating in a location such that a fragment from the warhead could penetrate

4902-521: The possibility that the explosive residue was the result of contamination from the aircraft's use in transporting troops during the Gulf War in 1991 or its use in a dog-training explosive-detection exercise about one month before the accident. 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 seawater (nearly all recovered wreckage

4988-455: The recovered airplane wreckage (described by the FBI as a piece of canvas-like material and two pieces of a floor panel). These samples were submitted to the FBI's laboratory in Washington, D.C., which determined that one sample contained traces of cyclotrimethylenetrinitramine ( RDX ), another nitroglycerin and the third a combination of RDX and pentaerythritol tetranitrate ( PETN ); these findings received much media attention. In addition,

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. The Sequencing Group concluded that the first event in

5160-485: The recovery operation's priorities. Although NTSB vice chairman Robert Francis stated that all bodies were retrieved as soon as they were spotted and that wreckage was recovered only if divers believed that victims were hidden underneath, many families were suspicious that investigators were not truthful or were withholding information. Anger and political pressure were also directed at Suffolk County medical examiner Charles V. Wetli as recovered bodies backlogged at

In one of the largest diver-assisted salvage operations ever conducted, often working in very difficult and dangerous conditions, more than 95% of the airplane wreckage was eventually recovered. The search-and-recovery effort identified three main areas of wreckage underwater, which were classified by color. The yellow, red, and green zones contained wreckage from the front, center, and rear sections of

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

5590-453: 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. Close examination of the wreckage revealed no evidence of structural faults such as fatigue , corrosion, or mechanical damage that could have caused

5676-412: The tank; with the CWT temperature raised to a sufficient level, a single ignition source could cause an explosion. Computer modeling and scale-model testing were used to predict and demonstrate how an explosion would progress in a 747 CWT. During this time, quenching was identified as an issue, a phenomenon in which the explosion would extinguish itself as it passed through the complex structure of

5762-547: The target track were unlikely to have been able to hear the explosions over the sound of their craft's engines and the noise of the hull traveling through water, especially if the occupants were in an enclosed bridge or cabin. Further, review of the Islip radar data for similar summer days and nights in 1999 indicated that the 30-knot track was consistent with normal commercial fishing, recreational, and cargo-vessel traffic. Trace amounts of explosive residue were detected on three samples of material from three separate locations of

5848-443: The thoroughness of the examinations was highly variable. Ultimately, the remains of all 230 victims were recovered and identified, and the final victim identification occurred more than 10 months after the crash. With lines of authority unclear, differences in agendas and culture between the FBI and NTSB resulted in discord. The FBI, assuming that a criminal act had occurred, saw the NTSB as indecisive. Expressing frustration at

5934-446: The undocumented removal by FBI agents of wreckage from the hangar where it was stored. Although considerable discrepancies existed among the many witness accounts, most had seen a "streak of light," described by 38 of 258 witnesses as ascending, moving to a point where a large fireball appeared. Several witnesses reported that the fireball divided into two parts as it descended toward the water. Intense public interest arose regarding

6020-421: The 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. These witness accounts were a major reason for the initiation and duration of the FBI's criminal investigation. Approximately 80 FBI agents conducted interviews with potential witnesses daily. No verbatim records of the witness interviews were produced; instead,

In all cases, the witnesses could not be describing a missile approaching an intact aircraft, as the plane had already exploded before their observations began. As the investigation progressed, the NTSB decided to form a witness group to more fully address the accounts of witnesses. From November 1996 through April 1997, this group reviewed summaries of witness accounts on loan from

6192-477: The witnesses. Despite the two and a half years that had elapsed since the accident, the witness group did interview the captain of Eastwind Airlines Flight 507, who was the first to report the explosion of TWA 800, because of his vantage point and experience as an airline pilot. 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 TWA press release gives 25. (TWA

6450-495: Was assembled in Washington, D.C., and arrived on the scene early the next morning. Meanwhile, initial witness descriptions led many to believe that the cause of the crash was a bomb or surface-to-air missile attack. As the NTSB does not investigate criminal activity, the United States Attorney General is empowered to declare an investigation to be potentially linked to a criminal act and to require

6536-411: Was correct, as Krick's birthday was on July 14th.) The ground-maintenance crew locked out the thrust reverser for engine No. 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, before Flight 800's departure. Additionally, severed cables for the engine No. 3 thrust reverser were replaced. During refueling of

6622-505: Was heard to say, "Look at that crazy fuel flow indicator there on number four... see that?" 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. This, together with the distribution of wreckage and witness reports, indicated a sudden, catastrophic in-flight breakup of TWA 800. Investigators considered several possible causes for

6708-400: Was immersed longer than two days). The NTSB concluded that it was "quite possible" that the explosive residue detected was transferred from military ships, ground vehicles, or the clothing and boots of military personnel onto the wreckage during or after the recovery operation, and that the residue was not present when the aircraft crashed into the water. Although it was unable to determine

6794-412: Was initiated by a fuel/air explosion in the CWT." 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

6880-465: Was killed in the explosion of TWA Flight 800 . Lychner, a former flight attendant for Trans World Airlines (TWA), bought a vacant house to sell in 1990. When she and her husband, Joe, visited it to meet who they believed was a prospective buyer, a workman from a cleaning company named William David Kelley appeared and told them that he forgot to clean under the sink. Later he tried to tear off her clothes; Joe held him as she called for help. Kelley,

6966-529: Was manufactured by Boeing in July 1971. The plane was purchased new by Trans World Airlines in 1971. The aircraft had completed 16,869 flights with 93,303 hours of operation and was powered by four Pratt & Whitney JT9D-7AH turbofan engines. On the day of the accident, the airplane departed from Ellinikon International Airport in Athens, Greece as TWA Flight 881 and arrived at John F. Kennedy International Airport (JFK) at about 4:38 p.m. The aircraft

7052-553: Was posted, visitors read the plaques, left roses, and touched the bronze. Joe often visited it. Lisa Gray of the Houston Press described it as "shamelessly emotional, a monument to a secular saint and her daughters." Pam Lychner State Jail , a state jail for men operated by the Texas Department of Criminal Justice in Atascocita , unincorporated Harris County , east of Humble , was named after her. In July 1995, it had been opened as Atascocita State Jail. After Pam's death,

Kevorkian, who had flown for TWA for 31 years and the U.S. Air Force for nine years and had logged 18,700 flight hours, including 5,400 on the Boeing 747. Captain/ check airman Steven E. Snyder, 57, had flown for TWA for 32 years and had logged 17,200 flight hours, including 4,700 on the Boeing 747. Flight engineer /check airman Richard G. Campbell Jr., 63, had flown for TWA for 30 years and

7224-489: Was requested from the Central Intelligence Agency (CIA). 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. This conclusion was reached after calculating how long the sound of the initial explosion took to reach

7310-568: Was the cause of the crash. The Federal Bureau of Investigation (FBI) and New York Police Department Joint Terrorism Task Force (JTTF) initiated a parallel criminal investigation. Sixteen months later, the JTTF announced that no evidence of a criminal act had been found and closed its active investigation. The four-year NTSB investigation concluded with the approval of the Aircraft Accident Report on August 23, 2000, ending

7396-464: Was the sun in relation to the aircraft and the missile launch point?" and "How long did the missile fly?" could have biased interviewees' responses in some cases. 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" and "did not view these apparently anomalous witness reports as persuasive evidence that some witnesses might have observed
