SummaryWreckage of missing Malaysia Airlines Flight MH 370 is believed to have sunk somewhere in Indian Ocean's depths.

If the wreckage of a missing Malaysia Airlines Flight MH 370 rests somewhere in the Indian Ocean's depths, investigators will likely need to entrust the hunt at least partly to robot submarines and the scientists who deploy them to scan remote swaths of the seafloor as two miles down or more and darker than night, the ocean becomes a particularly challenging place for human searchers.

Mystery of Malaysia Airline Flight MH370 may never be solved

The unmanned subs, called autonomous underwater vehicles or AUVs, played a critical role in locating the carcass of a lost Air France jet in 2011, two years after it crashed in the middle of the south Atlantic. The find allowed searchers to recover the black boxes of Malaysia Airlines Flight MH 370 that revealed the malfunctions behind the tragedy.

That search keyed off critical information: The search area for the Air France jet was much smaller than that for Malaysia Airlines Flight 370, and the first pieces of wreckage were recovered within days of the crash. Even then, it required two years and four deep water search missions before a team from the Woods Hole Oceanographic Institution, using an AUV equipped with side-scan sonar, located the jet about 12,800 feet (3,900 meters) underwater.

"Air France 447 is a bit different from Malaysian Air 370 in that we had a few more clues to work with," said Dave Gallo, who led the search team from Woods Hole, located on Massachusetts' Cape Cod. The independent research institution has offered its services to investigators but has not been asked to join the current search effort.
