Sounds from the Atlantic Ocean thought to be a signal from the black box onboard Air France flight 447 were not. Only pieces of the Airbus 330 that crashed en route from Rio de Janeiro to Paris killing 228 people onboard have been found, as French vessels and U.S. Navy ships continue to search for the data-recording device.
After a crash, the flight recorders send out “pingers” or locator beacons every second for 30 days, audible for up to 2 kilometers away. Time is running out for the search team, as the plane crashed into the Atlantic on May 31.
