Speaking on Gunter Jauch, a popular Sunday night talk show, the Lufthansa manager Kay Kratky said “it could be that the damage was so serious that it [the flight data recorder] is sending no signal.”
While the first black box, which contains audio recording from the cockpit was recovered soon after search and rescue teams arrived at the crash site, the second black box's whereabouts have remained elusive.
The plane is reckoned to have hit the crash site in the French Alps at a speed in the region of 800 kph, causing the plane to fragment and scatter over a wide area.
The impact, and the remote location of the crash site, have made recovery of objects vital in the search complicated.
