More than two dozen countries are searching for missing Malaysia Airlines Flight 370
Let's say they find it. Would the mystery be solved?
TWA Flight 800 and Air France Flight 447 provide clues about what could happen next
Some 25 countries are searching for missing Malaysia Airlines Flight 370 in an area nearly as big as the continental United States.
Let’s say they find it. Would the mystery be solved?
Hardly. Locating the aircraft is just the beginning.
Assuming the plane crashed and that it’s on the bottom of the ocean, search crews would face a myriad of obstacles in recovering parts of the plane and in piecing together what happened.
The experiences of TWA Flight 800 and Air France Flight 447 hint at the difficulties that might lie ahead.
The first demonstrates how tedious reconstruction work is and how important that work is to explaining exactly what went wrong, while the second shows just how long an ocean recovery can take.
“First thing to do is get back those recorders because … there’s a huge amount of data in the flight data recorder and the cockpit voice recorder. Get those back and then we can see what we need to do next. But, you know, time is of the essence,” said Tom Haueter, former director of the National Transportation Safety Board’s Office of Aviation Safety.
He knows what he’s talking about.
Debunking conspiracy theories
Haueter investigated the July 1996 crash of TWA Flight 800, which exploded in midair shortly after takeoff from New York City, killing all 230 people on board.
His job began at the bottom of the Atlantic Ocean. U.S. Navy and other divers spent more than 1,600 hours scouring for clues.
“We found pieces from just forward of the center section of the wing. Then we found the nose of the aircraft. And then we found the wings and the tail, the engines and everything else further down the flight path,” Haueter said.
The NTSB ruled that the explosion was caused by an electrical short circuit, which detonated the fuel tank and caused the Boeing 747 to break into pieces in the waters off Long Island.
The evidence was pieced together from a debris field of 75 square miles. Thousands of fragments were pulled from a tangled web of wires and airplane skin.
“We map the bottom. You start recovering things. You get back seat cushions, victim remains and what you do is X-ray everything – because you’re looking for an explosion. You’re looking for fast particles that may have been captured by a seat cushion or a body.” Haueter said.
As awful as it is to think about, recovered bodies can provide critical clues about a flight’s final moments.
Haueter again: “Take a look at all the information. Is there burning on the bodies beforehand? We’ll get autopsies. Is there soot in the trachea showing that there’s fire on board?”
In the case of TWA Flight 800, extracting the wreckage from the water and reconstructing it was critical to debunking various conspiracy theories.
Witnesses said they saw a streak of light and a fireball, leading to suspicions that terrorists struck the plane with a rocket. Others blamed a meteor or a missile.
Piecing the aircraft together was necessary to get a fuller picture.
“We take a look at everything we have here and what we couldn’t find anywhere in TWA was any evidence of being hit from a missile from the outside,” Haueter said.
Findings released three years after flight
Like that flight, the experience of Air France Flight 447 provides clues about what could happen if Malaysia Airlines Flight 370 is found at the bottom of the ocean.
On June 1, 2009, Air France Flight 447 was en route from Rio De Janeiro to Paris when communications ended suddenly from the Airbus A330.
Its last known position – two to four days by ship from the nearest ports – and the ocean’s depth hindered search efforts.
It took four searches over the course of nearly two years to locate the bulk of the wreckage and the majority of the 228 bodies in a mountain range deep under the ocean. It took even longer to find the cause of the disaster.
“We had three autonomous underwater vehicles – basically unmanned submarines that swim programmed tracks over the sea floor. They’d go back and forth using acoustic sensors to map the sea floor and from those maps we could detect the wreckage site,” said Mike Purcell with the Woods Hole Oceanographic Institution (WHOI).
In May 2011, the aircraft’s voice recorder and flight data recorder were recovered from the ocean floor after an extensive search.
It was not until July 2012 that investigators published their report, which blamed the crash on a series of errors by the pilots and a failure to react effectively to technical problems.
David Gallo, also with WHOI, helped lead the search for the recorders of Air France Flight 447.
He described what would happen once some debris from Malaysia Airlines Flight 370 is found, though he stressed there’s still no evidence the plane hit the water.
Because of currents, the wind and new information, the search area is getting bigger by the day.
“Once a piece of the debris is found – if it did impact on the water – then you’ve got to backtrack that debris to try to find the ‘X marks the spot’ on where the plane actually hit the water, because that would be the center of the haystack.
“And in that haystack you’re trying to find bits of that needle – in fact, in the case of the flight data recorders, you’re looking for a tiny little bit of that needle,” he said.
