Remember TWA Flight 800 - the doomed plane that exploded shortly after taking off from JFK Airport ten years ago? Your answer is probably yes. Remember exactly what caused it to explode and crash? Your answer is probably no. Chances are you remember that there was some controversy over the possibility that a terrorist missile (or even an accidentally fired domestic one) destroyed the plane.

The eventual verdict from the National Transportation Safety Board was less sinister...but perhaps scarier. The agency said the center fuel tank exploded as a result of an electrical short circuit. Scarier yet, the NTSB said other older planes still flying were in similar danger of exploding.

This tenth anniversary documentary called No Survivors -- Why TWA 800 Could Happen Again examines the NTSB's conclusion, the conspiracy theories and, perhaps most poignant, the ongoing nightmares of the victims' families who still suspect the government knows more than it is saying.

Oh, and those aging fuel tanks? The FAA is still trying to get the airlines to install safety equipment to prevent other such explosions. According to CNN executive producer Mark Nelson, "The industry says it's too expensive and unnecessary."
