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 say the crash was due to a U.S. Navy missile test gone awry , a terrorist missile strike , or an on-board bomb . On June 19 , 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
