TWA Flight 800 conspiracy theories are discredited alternative explanations of the crash of Trans World Airlines Flight 800 (TWA 800) in 1996.[1] 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. Conspiracy theories claim that the crash was due to a U.S. Navy missile test gone awry, a terrorist missile strike, or an on-board bomb. In 2013, a documentary alleging that the investigation into the crash was a cover-up made news headlines with statements from six members of the original investigation team, now retired, who also filed a petition to reopen the probe.[2]
