Just read this story and all I could say is why? Some former NTSB retirees have come forward after retirement when their bosses can no longer threaten them and said that multiple eyewitness accounts of a missile ascending from the ground to TWA 800 are correct and the investigation did turn up evidence of an explosion and that the official version of fuel vapors in a tank simply reaching their flash point and igniting was all a lie and coverup. They claim the CIA intimidated them into covering up the real evidence. If this is true then who is really responsible and what is the reason for the coverup? If it was an act of terrorism then why cover it up?
