A group of former NTSB investigators argue in an upcoming documentary that the crash, which occurred off the coast of Long Island in 1996 and killed 230 people, was not caused by a fuel tank explosion, as the agency said.
The group officially petitioned the National Transportation Safety Board to reconsider the results of its original, exhaustive four-year probe: The plane was brought down by an explosion in its center fuel tank, ignited by an electrical short circuit.
Stalcup, joined Wednesday by former NTSB investigator Hank Hughes and former TWA investigator Bob Young, said they had no doubt that a missile was responsible for the plane's demise.
"What they portrayed as the cause of the accident is not true," said Hughes. "I've conducted hundreds of investigations over a long period of time. If it smells like a rat, and looks like a rat, after a while you get the idea it's a rat."
The NTSB issued a statement responding to the reinvestigation request. Conspiracy theories surrounding the plane's demise began circulating within days of its crash off Long Island.
"While the NTSB rarely re-investigates issues that have already been examined, our investigations are never closed and we can review any new information," the federal agency said.
