Paris, June 23(ANI): Signals from the flight data recorder, or the black boxes of the Air France flight that crashed into the Atlantic ocean killing all 228 passengers onboard, has been located.

“A French naval vessel has detected a weak signal from the flight data recorders, and a mini submarine was dispatched on Monday to try and find the black boxes at the bottom of the ocean floor,” The Telegraph quoted a French newspaper Le Monde.

The Air France plane had sent out 24 system failure alerts before disappearing, and it is believed that the black boxes may contain vital information that could help explain what happened when the Airbus A330 crashed into the sea on June 1.

French vessels involved in the search operation include a nuclear submarine with advanced sonar equipment, and a research ship equipped with mini submarines.

The remote location in the Atlantic as well as the depth and surface of the ocean floor have made the search especially difficult, and the wreckage could lie anywhere between a depth of 1 km and 4 km.

However, an Air France spokeswoman said that she could not confirm the report. (ANI)
