On Wednesday, July 17, 1996, at 8:19 p.m., TWA Flight 800 took off from JFK airport and headed out over Long Island toward Paris. Twelve minutes later, TWA 800 exploded mid-air, killing all 230 people on board. Twenty years later, the crash of TWA 800 remains a subject of horror and fascination. Conspiracy theorists still insist that TWA 800 was brought down, deliberately or accidentally, potentially by the US military - despite a four-year-long investigation, the most expensive in aviation history, which found that a short circuit in the plane's center wing fuel tank caused the crash. In his new book TWA 800: The Crash, the Cover-Up, and the Conspiracy," author Jack Cashill maintains that the plane was brought down by external forces and that the government has engaged in a decades-long cover-up. Cashill doesn't offer a definitive alternate cause, but the strongest portion of his book are reprints of multiple witness statements, taken by the FBI and CIA in the immediate aftermath. Over 700 of these have since been made public; in them, 258 witnesses told investigators they'd seen a streak of white light approaching the aircraft before the explosion. A few witnesses used the word "rocket" or "missile" in describing what they saw. These vivid, first-hand accounts remain in stark contrast to the final report - and at the time, every possibility was investigated.
