A French nuclear submarine has joined the search for Air France Flight 447’s black boxes, ABC News reports. The sub boasts high-tech sonar equipment, which could help detect the acoustic signals the flight recorders transmit. The sub will work alongside a French research vessel set to arrive Friday, carrying underwater robots and equipment necessary to retrieve the boxes should they be found.
More bodies were found last night, bringing the total up to 41. There were 228 people aboard when the plane went down. Investigators hope the bodies will provide clues as to what caused the crash. Current speculation is centered on the plane’s speed sensor, which appears to have malfunctioned. Airlines worldwide are busily replacing the sensors on their fleets’ Airbus jets.
