Family members of the 230 victims of the TWA Flight 800 crash gathered with those who tried to rescue their loved ones on a Long Island beach to mark the 20th anniversary of the disaster.
Current and former federal officials who played key roles in the investigation of one of the nation's worst aviation disasters said Tuesday they stand by their conclusion that the explosion of TWA flight 800 was caused by overheated fuel tank vapors, and not a bomb or missile.
