"After missile visibility tests were conducted in April 2000, at Because of their unique vantage points or the level of precision and detail provided in their accounts, five witness accounts generated special interest:The NTSB concluded that "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 post-explosion, preimpact breakup sequence".To determine what ignited the flammable fuel-air vapor in the CWT and caused the explosion, the NTSB evaluated numerous potential ignition sources. Three decades have passed since 92 lives were lost on the west slope of Mount Weather, but memories of what happened that … December 1st, 1974. Photograph by James W. Bailey. On December 1, 1974, TWA Flight 514, bound for Washington from Indianapolis, crashed into the peak of Mt. Before the meeting adjourned, it was agreed that the organization should be named after the General. 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. Numerous heavy components of the aircraft were thrown forward of the outcropping, and numerous intense post-impact fires broke out which were later extinguished. The Boeing 727 had been diverted to Dulles due to poor weather conditions. The plane did, however, cut power lines around the secret center of the Army interagency communications unit near the crash site, causing the teletype machines in 25 news and telephone company offices across the country to start transmitting garbled copy. All but one were considered very unlikely to have been the source of ignition.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 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.Similarly, the investigation considered the possibility that a small explosive charge placed on the CWT could have been the ignition source.The NTSB also investigated whether the fuel/air mixture in the CWT could have been ignited by 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. He challenged those in attendance to continue to get to know each other, help to mentor junior officers, and help each other whenever possible. The worst air disaster of 1974, TWA Flight 514 was mentioned in the closing of the second chapter of Mark Oliver Everett's book "Things the Grandchildren Should Know", as well as the crash, its aftermath, and its repercussions are the subject of "Sound of Impact: The Legacy of TWA Flight 514" by Adam Shaw. Two state troopers found the wreckage almost immediately, hampered by driving ram, fog and winds gusting up to 40-50 miles an hour.Rescue workers found the woods littered with broken bodies, blazing debris and splintered timber. Weather in Upperville Virginia. Federal Land... Mount Weather started its service to the United States near the turn of the Twentieth century – the site of a National Weather Bureau facility where balloons and box … All 85 passengers and 7 crew members were killed. The site was brought into the public eye by The Washington Post, when the government facility was mentioned while reporting on the December 1, 1974, crash into Mount Weather of TWA Flight 514, a Boeing 727 jetliner. The Crash of TWA Flight 514. When investigative priority remains with the NTSB, the FBI must coordinate its investigative activities with the NTSB investigator-in-charge. Three decades have passed since 92 lives were lost on the west slope of Mount Weather, but memories of what happened that rainy day on the Blue Ridge still linger. "In order to evaluate the sequence of structural breakup of the airplane, the NTSB formed the Sequencing Group,Because there was no evidence 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.In order 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 a retired 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,"Recovery locations of the wreckage from the ocean (the red, yellow, and green zones) clearly indicated that: (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.Fire damage and soot deposits on the recovered wreckage indicated that some areas of fire existed on the airplane as it continued in crippled flight after the loss of the forward fuselage.At the start of FBI's investigation, because of the possibility that international terrorists might have been involved, assistance was requested from the CIA (US As the investigation progressed, the NTSB decided to form a witness group to more fully address the accounts of witnesses.In February 1998, the FBI, having closed its active investigation, agreed to fully release the witness summaries to the NTSB.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.
